Kevin Wolf d926f4ddd2 iotests: Skip read-only cases in 118 when run as root
Some tests in 118 use chmod to remove write permissions from the file
and assume that the image can indeed not be opened read-write
afterwards. This doesn't work when the test is run as root, because root
can still open the file as writable even when the permission bit isn't
set.

Introduce a @skip_if_root decorator and use it in 118 to skip the tests
in question when the script is run as root.

Stefan Hajnoczi d08f68b8e8 libqos: add VIRTIO PCI 1.0 support
Implement the VIRTIO 1.0 virtio-pci interface.  The main change here is
that the register layout is no longer a fixed layout in BAR 0.  Instead
we have to iterate of PCI Capabilities to find descriptions of where
various registers are located.  The vring registers are also more
fine-grained, allowing for more flexible vring layouts, but we don't
take advantage of that.

Stefan Hajnoczi c0f79698ed libqos: implement VIRTIO 1.0 FEATURES_OK step
Device initialization has an extra step in VIRTIO 1.0.  The FEATURES_OK
status bit is set to indicate that feature negotiation has completed.
The driver then reads the status register again to check that the device
agrees with the final features.

Implement this step as part of qvirtio_set_features() instead of
introducing a separate function.  This way all existing code works
without modifications.

The check in qvirtio_set_driver_ok() needs to be updated because
FEATURES_OK will be set for VIRTIO 1.0 devices.

There was no real virtio-mmio ABI change between Legacy and VIRTIO 1.0
except that the Version field was incremented from 1 to 2.

However, QEMU does not allow Legacy drivers to perform VIRTIO 1.0
operations like accessing 64-bit feature bits.  Since we will introduce
64-bit feature bit support we need a way to differentiate between
virtio-mmio Version 1 and 2 to avoid upsetting QEMU when we operate in
Legacy mode.

Stash away the Version field so later patches can change behavior
depending on the version.

Peter Krempa 23394b4c39 qapi: Add feature flags to commands
Similarly to features for struct types introduce the feature flags also
for commands. This will allow notifying management layers of fixes and
compatible changes in the behaviour of a command which may not be
detectable any other way.

The changes were heavily inspired by commit 6a8c0b5102.

Markus Armbruster e6c42b96b9 qapi: Split up scripts/qapi/common.py
The QAPI code generator clocks in at some 3100 SLOC in 8 source files.
Almost 60% of the code is in qapi/common.py.  Split it into more
focused modules:

* Move QAPISchemaPragma and QAPISourceInfo to qapi/source.py.

* Move QAPIError and its sub-classes to qapi/error.py.

* Move QAPISchemaParser and QAPIDoc to parser.py.  Use the opportunity
  to put QAPISchemaParser first.

* Move check_expr() & friends to qapi/expr.py.  Use the opportunity to
  put the code into a more sensible order.

* Move QAPISchema & friends to qapi/schema.py

* Move QAPIGen and its sub-classes, ifcontext,
  QAPISchemaModularCVisitor, and QAPISchemaModularCVisitor to qapi/gen.py

* Delete camel_case(), it's unused since commit e98859a9b9 "qapi:
  Clean up after recent conversions to QAPISchemaVisitor"

A number of helper functions remain in qapi/common.py.  I considered
moving the code generator helpers to qapi/gen.py, but decided not to.
Perhaps we should rewrite them as methods of QAPIGen some day.

Markus Armbruster f01338cce6 qapi: Speed up frontend tests
"make check-qapi-schema" takes around 10s user + system time for me.
With -j, it takes a bit over 3s real time.  We have worse tests.  It's
still annoying when you work on the QAPI generator.

Some 1.4s user + system time is consumed by make figuring out what to
do, measured by making a target that does nothing.  There's nothing I
can do about that right now.  But let's see what we can do about the
other 8s.

Almost 7s are spent running test-qapi.py for every test case, the rest
normalizing and diffing test-qapi.py output.  We have 190 test cases.

If I downgrade to python2, it's 4.5s, but python2 is a goner.

Hacking up test-qapi.py to exit(0) without doing anything makes it
only marginally faster.  The problem is Python startup overhead.

Our configure puts -B into $(PYTHON).  Running without -B is faster:
4.4s.

We could improve the Makefile to run test cases only when the test
case or the generator changed.  But I'm after improvement in the case
where the generator changed.

test-qapi.py is designed to be the simplest possible building block
for a shell script to do the complete job (it's actually a Makefile,
not a shell script; no real difference).  Python is just not meant for
that.  It's for bigger blocks.

Move the post-processing and diffing into test-qapi.py, and make it
capable of testing multiple schema files.  Set executable bits while
there.

Running it once per test case now takes slightly longer than 8s.  But
running it once for all of them takes under 0.2s.

Messing with the Makefile to run it only on the tests that need
retesting is clearly not worth the bother.

Expected error output changes because the new normalization strips off
$(SRCDIR)/tests/qapi-schema/ instead of just $(SRCDIR)/.

The .exit files go away, because there is no exit status to test
anymore.

Markus Armbruster f3d4aa5add qapi: Don't suppress doc generation without pragma doc-required
Commit bc52d03ff5 "qapi: Make doc comments optional where we don't
need them" made scripts/qapi2texi.py fail[*] unless the schema had
pragma 'doc-required': true.  The stated reason was inability to cope
with incomplete documentation.

When commit fb0bc835e5 "qapi-gen: New common driver for code and doc
generators" folded scripts/qapi2texi.py into scripts/qapi-gen.py, it
turned the failure into silent suppression.

The doc generator can cope with incomplete documentation now.  I don't
know since when, or what the problem was, or even whether it ever
existed.

Drop the silent suppression.

[*] The fail part was broken, fixed in commit e8ba07ea9a.

Vladimir Sementsov-Ogievskiy 48557b1383 util/hbitmap: strict hbitmap_reset
hbitmap_reset has an unobvious property: it rounds requested region up.
It may provoke bugs, like in recently fixed write-blocking mode of
mirror: user calls reset on unaligned region, not keeping in mind that
there are possible unrelated dirty bytes, covered by rounded-up region
and information of this unrelated "dirtiness" will be lost.

Make hbitmap_reset strict: assert that arguments are aligned, allowing
only one exception when @start + @count == hb->orig_size. It's needed
to comfort users of hbitmap_next_dirty_area, which cares about
hb->orig_size.

Igor Mammedov 021a007efc tests: cpu-plug-test: fix device_add for pc/q35 machines
Commit bc1fb850a3 silently broke device_add test for CPU hotplug which
resulted in test successfully passing though it wasn't actually run.
Fix it by making sure that all non present CPUs reported
by "query-hotpluggable-cpus" are hotplugged instead of making up
and hardcoding values.

Use of query-hotpluggable-cpus also allows consolidatiate device_add
cpu testcases and reuse the same test function for all targets.

While at it also add a check that at least one CPU was hotplugged,
to avoid silent breakage in the future.

Fixes: bc1fb850a3 (vl.c deprecate incorrect CPUs topology)

Convert the ptimer test cases to the transaction-based ptimer API,
by changing to ptimer_init(), dropping the now-unused QEMUBH
variables, and surrounding each set of changes to the ptimer

Peter Maydell b01422622b ptimer: Rename ptimer_init() to ptimer_init_with_bh()
Currently the ptimer design uses a QEMU bottom-half as its
mechanism for calling back into the device model using the
ptimer when the timer has expired. Unfortunately this design
is fatally flawed, because it means that there is a lag
between the ptimer updating its own state and the device
callback function updating device state, and guest accesses
to device registers between the two can return inconsistent
device state.

We want to replace the bottom-half design with one where
the guest device's callback is called either immediately
(when the ptimer triggers by timeout) or when the device
model code closes a transaction-begin/end section (when the
ptimer triggers because the device model changed the
ptimer's count value or other state). As the first step,
rename ptimer_init() to ptimer_init_with_bh(), to free up
the ptimer_init() name for the new API. We can then convert
all the ptimer users away from ptimer_init_with_bh() before
removing it entirely.

(Commit created with
 git grep -l ptimer_init | xargs sed -i -e 's/ptimer_init/ptimer_init_with_bh/'
and three overlong lines folded by hand.)

Max Reitz a1406a9262 iotests: Test large write request to qcow2 file
Without HEAD^, the following happens when you attempt a large write
request to a qcow2 file such that the number of bytes covered by all
clusters involved in a single allocation will exceed INT_MAX:

(A) handle_alloc_space() decides to fill the whole area with zeroes and
    fails because bdrv_co_pwrite_zeroes() fails (the request is too
    large).

(B) If handle_alloc_space() does not do anything, but merge_cow()
    decides that the requests can be merged, it will create a too long
    IOV that later cannot be written.

(C) Otherwise, all parts will be written separately, so those requests
    will work.

In either B or C, though, qcow2_alloc_cluster_link_l2() will have an
overflow: We use an int (i) to iterate over nb_clusters, and then
calculate the L2 entry based on "i << s->cluster_bits" -- which will
overflow if the range covers more than INT_MAX bytes.  This then leads
to image corruption because the L2 entry will be wrong (it will be
recognized as a compressed cluster).

Even if that were not the case, the .cow_end area would be empty
(because handle_alloc() will cap avail_bytes and nb_bytes at INT_MAX, so
their difference (which is the .cow_end size) will be 0).

So this test checks that on such large requests, the image will not be
corrupted.  Unfortunately, we cannot check whether COW will be handled
correctly, because that data is discarded when it is written to null-co
(but we have to use null-co, because writing 2 GB of data in a test is
not quite reasonable).

Max Reitz 48c8d3ce6d iotests/028: Fix for long $TEST_DIRs
For long test image paths, the order of the "Formatting" line and the
"(qemu)" prompt after a drive_backup HMP command may be reversed.  In
fact, the interaction between the prompt and the line may lead to the
"Formatting" to being greppable at all after "read"-ing it (if the
prompt injects an IFS character into the "Formatting" string).

So just wait until we get a prompt.  At that point, the block job must
have been started, so "info block-jobs" will only return "No active
jobs" once it is done.

Alberto Garcia f2208fdc5b block: Reject misaligned write requests with BDRV_REQ_NO_FALLBACK
The BDRV_REQ_NO_FALLBACK flag means that an operation should only be
performed if it can be offloaded or otherwise performed efficiently.

However a misaligned write request requires a RMW so we should return
an error and let the caller decide how to proceed.

This hits an assertion since commit c8bb23cbdb if the required
alignment is larger than the cluster size:

qemu-img create -f qcow2 -o cluster_size=2k img.qcow2 4G
qemu-io -c "open -o driver=qcow2,file.align=4k blkdebug::img.qcow2" \
        -c 'write 0 512'
qemu-io: block/io.c:1127: bdrv_driver_pwritev: Assertion `!(flags & BDRV_REQ_NO_FALLBACK)' failed.
Aborted

The reason is that when writing to an unallocated cluster we try to
skip the copy-on-write part and zeroize it using BDRV_REQ_NO_FALLBACK
instead, resulting in a write request that is too small (2KB cluster
size vs 4KB required alignment).

Stefan Hajnoczi 69de48445a test-bdrv-drain: fix iothread_join() hang
tests/test-bdrv-drain can hang in tests/iothread.c:iothread_run():

  while (!atomic_read(&iothread->stopping)) {
      aio_poll(iothread->ctx, true);
  }

The iothread_join() function works as follows:

  void iothread_join(IOThread *iothread)
  {
      iothread->stopping = true;
      aio_notify(iothread->ctx);
      qemu_thread_join(&iothread->thread);

If iothread_run() checks iothread->stopping before the iothread_join()
thread sets stopping to true, then aio_notify() may be optimized away
and iothread_run() hangs forever in aio_poll().

The correct way to change iothread->stopping is from a BH that executes
within iothread_run().  This ensures that iothread->stopping is checked
after we set it to true.

This was already fixed for ./iothread.c (note this is a different source
file!) by commit 2362a28ea1 ("iothread:
fix iothread_stop() race condition"), but not for tests/iothread.c.

Eric Auger 9a85e4b8f6 migration: Support gtree migration
Introduce support for GTree migration. A custom save/restore
is implemented. Each item is made of a key and a data.

If the key is a pointer to an object, 2 VMSDs are passed into
the GTree VMStateField.

When putting the items, the tree is traversed in sorted order by
g_tree_foreach.

On the get() path, gtrees must be allocated using the proper
key compare, key destroy and value destroy. This must be handled
beforehand, for example in a pre_load method.

Tests are added to test save/dump of structs containing gtrees
including the virtio-iommu domain/mappings scenario.

Vladimir Sementsov-Ogievskiy 00e30f05de block/backup: use backup-top instead of write notifiers
Drop write notifiers and use filter node instead.

= Changes =

1. Add filter-node-name argument for backup qmp api. We have to do it
in this commit, as 257 needs to be fixed.

2. There are no more write notifiers here, so is_write_notifier
parameter is dropped from block-copy paths.

3. To sync with in-flight requests at job finish we now have drained
removing of the filter, we don't need rw-lock.

4. Block-copy is now using BdrvChildren instead of BlockBackends

5. As backup-top owns these children, we also move block-copy state
into backup-top's ownership.

= Iotest changes =

56: op-blocker doesn't shoot now, as we set it on source, but then
check on filter, when trying to start second backup.
To keep the test we instead can catch another collision: both jobs will
get 'drive0' job-id, as job-id parameter is unspecified. To prevent
interleaving with file-posix locks (as they are dependent on config)
let's use another target for second backup.

Also, it's obvious now that we'd like to drop this op-blocker at all
and add a test-case for two backups from one node (to different
destinations) actually works. But not in these series.

141: Output changed: prepatch, "Node is in use" comes from bdrv_has_blk
check inside qmp_blockdev_del. But we've dropped block-copy blk
objects, so no more blk objects on source bs (job blk is on backup-top
filter bs). New message is from op-blocker, which is the next check in
qmp_blockdev_add.

257: The test wants to emulate guest write during backup. They should
go to filter node, not to original source node, of course. Therefore we
need to specify filter node name and use it.

Max Reitz e6e8db0337 iotests: Fix 125 for growth_mode = metadata
If we use growth_mode = metadata, it is very much possible that the file
uses more disk space after we have written something to the added area.
We did indeed want to test for this case, but unfortunately we evidently
just copied the code from the "Test creation preallocation" section and
forgot to replace "$create_mode" by "$growth_mode".

We never noticed because we only read the first number from qemu-img
info's "disk size" output -- and that is effectively useless, because
qemu-img prints a human-readable value (which generally includes a
decimal point).  That will be fixed in the patch after the next one.

Upcoming asynchronous handling of sub-parts of qcow2 requests will
change number of leaked clusters and even make it racy. As a
preparation, ignore leaks on failure parts in 026.

It's not trivial to just grep or substitute qemu-img output for such
thing. Instead do better: 3 is a error code of qemu-img check, if only
leaks are found. Catch this case and print success output.

Max Reitz 4d804b5305 iotests/262: Switch source/dest VM launch order
Launching the destination VM before the source VM gives us a regression
test for HEAD^:

The guest device causes a read from the disk image through
guess_disk_lchs().  This will not work if the first sector (containing
the partition table) is yet unallocated, we use COR, and the node is
inactive.

By launching the source VM before the destination, however, the COR
filter on the source will allocate that area in the image shared between
both VMs, thus the problem will not become apparent.

Switching the launch order causes the sector to still be unallocated
when guess_disk_lchs() runs on the inactive node in the destination VM,
and thus we get our test case.

Laszlo Ersek 037973bb0d edk2 build scripts: work around TianoCore#1607 without forcing Python 2
It turns out that forcing python2 for running the edk2 "build" utility is
neither necessary nor sufficient.

Forcing python2 is not sufficient for two reasons:

- QEMU is moving away from python2, with python2 nearing EOL,

- according to my most recent testing, the lacking dependency information
  in the makefiles that are generated by edk2's "build" utility can cause
  parallel build failures even when "build" is executed by python2.

And forcing python2 is not necessary because we can still return to the
original idea of filtering out jobserver-related options from MAKEFLAGS.
So do that.

While at it, cut short edk2's auto-detection of the python3.* minor
version, by setting PYTHON_COMMAND to "python3" (which we expect to be
available wherever we intend to build edk2).

With this patch, the guest UEFI binaries that are used as part of the BIOS
tables test, and the OVMF and ArmVirtQemu platform firmwares, will be
built strictly in a single job, regardless of an outermost "-jN" make
option. Alas, there appears to be no reliable way to build edk2 in an
(outer make, inner make) environment, with a jobserver enabled.

Thomas Huth 3d5e90a50b Disallow colons in the parameter of "-accel"
Everybody who used something like "-machine accel=kvm:tcg" in the past
might be tempted to specify a similar list with the -accel parameter,
too, for example "-accel kvm:tcg". However, this is not how this
options is thought to be used, since each "-accel" should only take care
of one specific accelerator.

In the long run, we really should rework the "-accel" code completely,
so that it does not set "-machine accel=..." anymore internally, but
is completely independent from "-machine". For the short run, let's
make sure that users cannot use "-accel xyz:tcg", so that we avoid
that we have to deal with such cases in the wild later.

Markus Armbruster c615550df3 qapi: Improve source file read error handling
qapi-gen.py crashes when it can't open the main schema file, and when
it can't read from any schema file.  Lazy.

Change QAPISchema.__init__() to take a file name instead of a file
object.  Move the open code from _include() to __init__(), so it's
used for the main schema file, too.

Move the read into the try for good measure, and rephrase the error
message.

Reporting open or read failure for the main schema file needs a
QAPISourceInfo representing "no source".  Make QAPISourceInfo cope
with fname=None.

For what it's worth, the GNU Coding Standards advise the message
"should not begin with a capital letter when it follows a program name
and/or file name, because that isn’t the beginning of a sentence. (The
sentence conceptually starts at the beginning of the line.)"

While there, avoid breaking lines containing multiple arguments in the

Markus Armbruster 638c4af931 qapi: Clean up member name case checking
QAPISchemaMember.check_clash() checks for member names that map to the
same c_name().  Takes care of rejecting duplicate names.

It also checks a naming rule: no uppercase in member names.  That's a
rather odd place to do it.  Enforcing naming rules is
check_name_str()'s job.

qapi-code-gen.txt specifies the name case rule applies to the name as
it appears in the schema.  check_clash() checks c_name(name) instead.
No difference, as c_name() leaves alone case, but unclean.

Move the name case check into check_name_str(), less the c_name().
New argument @permit_upper suppresses it.  Pass permit_upper=True for
definitions (which are not members), and when the member's owner is
whitelisted with pragma name-case-whitelist.

Bonus: name-case-whitelist now applies to a union's inline base, too.
Update qapi/qapi-schema.json pragma to whitelist union CpuInfo instead
of CpuInfo's implicit base type's name q_obj_CpuInfo-base.

e.g.

    tests/qapi-schema/alternate-any.json:2: alternate 'Alt' member 'one' cannot use type 'any'

But not always:

    tests/qapi-schema/enum-if-invalid.json:2: 'if' condition must be a string or a list of strings

Instead of improving them one by one, report the offending expression
whenever it is known, like this:

    tests/qapi-schema/enum-if-invalid.json: In enum 'TestIfEnum':
    tests/qapi-schema/enum-if-invalid.json:2: 'if' condition must be a string or a list of strings

Error messages that mention the offending expression become a bit
redundant, e.g.

    tests/qapi-schema/alternate-any.json: In alternate 'Alt':
    tests/qapi-schema/alternate-any.json:2: alternate 'Alt' member 'one' cannot use type 'any'

I'll take care of that later in this series.

Michal Privoznik 2546be1c85 qmp-dispatch: Use CommandNotFound error for disabled commands
If a command is disabled an error is reported.  But due to usage of
error_setg() the class of the error is GenericError which does not
help callers in distinguishing this case from a case where a qmp
command fails regularly due to other reasons.

We used to use class CommandDisabled until the great error
simplification (commit de253f1491 for QMP and commit 93b91c59db for
qemu-ga, both v1.2.0).

Use CommandNotFound error class, which is close enough.

Alex Bennée 80394ccf21 tests/docker: remove debian-powerpc-user-cross
Despite our attempts in 4d26c7fef4 to keep this going it still gets in
the way of "make docker-test-build" completing because of course we
can't build a modern QEMU with the image. Let's put the thing out of
its misery and remove it.

People who really care about building on powerpc can still use the
binfmt_misc support to manually build an image (or just run the build
from pre this commit).

John Snow bcbf279473 docker: move tests from python2 to python3
As part of the push to drop python2 support, replace any explicit python2
dependencies with python3 versions.

For centos, python2 still exists as an implicit dependency, but by adding
python3 we will be able to build even if the configure script begins to
require python 3.5+.

Tested with centos7, fedora, ubuntu, ubuntu1804, and debian 9 (amd64).
Tested under a custom configure script that requires Python 3.5+.

the travis dockerfile is also moved to using python3, which was tested
by running `make docker-test-build@travis`, which I hope is sufficient.

We declare the test binaries as PHONY as they don't really exist.

otherwise variable value so we could compare the record and replay
outputs and ensure they match]

Eric Blake 1b5c15cebd nbd/client: Add hint when TLS is missing
I received an off-list report of failure to connect to an NBD server
expecting an x509 certificate, when the client was attempting something
similar to this command line:

$ ./x86_64-softmmu/qemu-system-x86_64 -name 'blah' -machine q35 -nodefaults \
  -object tls-creds-x509,id=tls0,endpoint=client,dir=$path_to_certs \
  -device virtio-scsi-pci,id=virtio_scsi_pci0,bus=pcie.0,addr=0x6 \
  -drive id=drive_image1,if=none,snapshot=off,aio=threads,cache=none,format=raw,file=nbd:localhost:9000,werror=stop,rerror=stop,tls-creds=tls0 \
  -device scsi-hd,id=image1,drive=drive_image1,bootindex=0
qemu-system-x86_64: -drive id=drive_image1,if=none,snapshot=off,aio=threads,cache=none,format=raw,file=nbd:localhost:9000,werror=stop,rerror=stop,tls-creds=tls0: TLS negotiation required before option 7 (go)
server reported: Option 0x7 not permitted before TLS

The problem?  As specified, -drive is trying to pass tls-creds to the
raw format driver instead of the nbd protocol driver, but before we
get to the point where we can detect that raw doesn't know what to do
with tls-creds, the nbd driver has already failed because the server
complained.  The fix to the broken command line?  Pass
'...,file.tls-creds=tls0' to ensure the tls-creds option is handed to
nbd, not raw.  But since the error message was rather cryptic, I'm
trying to improve the error message.

With this patch, the error message adds a line:

qemu-system-x86_64: -drive id=drive_image1,if=none,snapshot=off,aio=threads,cache=none,format=raw,file=nbd:localhost:9000,werror=stop,rerror=stop,tls-creds=tls0: TLS negotiation required before option 7 (go)
Did you forget a valid tls-creds?
server reported: Option 0x7 not permitted before TLS

And with luck, someone grepping for that error message will find this
commit message and figure out their command line mistake.  Sadly, the
only mention of file.tls-creds in our docs relates to an --image-opts
use of PSK encryption with qemu-img as the client, rather than x509
certificate encryption with qemu-kvm as the client.

Markus Armbruster dec0012ef8 qapi: Fix missing 'if' checks in struct, union, alternate 'data'
Commit 87adbbffd4..3e270dcacc "qapi: Add 'if' to (implicit
struct|union|alternate) members" (v4.0.0) neglected test coverage, and
promptly failed to check the conditions.  Review fail.

Recent commit "tests/qapi-schema: Demonstrate insufficient 'if'
checking" added test coverage, demonstrating the bug.  Fix it by add
the missing check_if().

Markus Armbruster 887a2069f7 qapi: Fix broken discriminator error messages
check_union() checks the discriminator exists in base and makes sense.
Two error messages mention the base.  These are broken for anonymous
bases, as demonstrated by tests flat-union-invalid-discriminator and
flat-union-invalid-if-discriminator.err.  The third one doesn't
bother.

First broken when commit ac4338f8eb "qapi: Allow anonymous base for
flat union" (v2.6.0) neglected to adjust the "not a member of base"
error message.  Commit ccadd6bcba "qapi: Add 'if' to implicit struct
members" (v4.0.0) then cloned the flawed error message.

Dumb them down not to mention the base.

Markus Armbruster 9d55380b5a qapi: Remove null from schema language
We represent the parse tree as OrderedDict.  We fetch optional dict
members with .get().  So far, so good.

We represent null literals as None.  .get() returns None both for
"absent" and for "present, value is the null literal".  Uh-oh.

Test features-if-invalid exposes this bug: "'if': null" is
misinterpreted as absent "if".

We added null to the schema language to "allow [...] an explicit
default value" (commit e53188ada5 "qapi: Allow true, false and null in
schema json", v2.4.0).  Hasn't happened; null is still unused except
as generic invalid value in tests/.

To fix, we'd have to replace .get() by something more careful, or
represent null differently.  Feasible, but we got more and bigger fish
to fry right now.  Remove the null literal from the schema language.
Replace null in tests by another invalid value.

Test features-if-invalid now behaves as it should.

Markus Armbruster cd346bdc46 tests/qapi-schema: Demonstrate misleading optional tag error
Test flat-union-optional-discriminator declares its union tag as
'*switch': 'Enum', and points to it with 'discriminator': '*switch'.
This gets rejected as "discriminator of flat union 'MyUnion' uses
invalid name '*switch'".  Correct; member 'discriminator' doesn't
accept a '*' prefix.

However, this merely tests name validity checking, which we already
cover elsewhere.  More interesting is testing the valid name 'switch'.
This reports "discriminator 'switch' is not a member of base struct
'Base'", which is misleading.

Copy the existing 'discriminator': '*switch' test to
flat-union-discriminator-bad-name, and rewrite its comment.  Change
flat-union-optional-discriminator to test 'discriminator': 'switch',
and mark it FIXME.
