Thomas Huth efd0e5a121 iotests: Skip test 060 if it is not possible to create large files
Test 060 fails in the arm64, s390x and ppc64le LXD containers on Travis
(which we will hopefully enable in our CI soon). These containers
apparently do not allow large files to be created. The repair process
in test 060 creates a file of 64 GiB, so test first whether such large
files are possible and skip the test if that's not the case.

Thomas Huth 059f708d0c iotests: Provide a function for checking the creation of huge files
Some tests create huge (but sparse) files, and to be able to run those
tests in certain limited environments (like CI containers), we have to
check for the possibility to create such files first. Thus let's introduce
a common function to check for large files, and replace the already
existing checks in the iotests 005 and 220 with this function.

Vladimir Sementsov-Ogievskiy d936613547 nbd: assert that Error** is not NULL in nbd_iter_channel_error
All callers of nbd_iter_channel_error() pass the address of a
local_err variable, and only call this function if an error has
already occurred, using this function to propagate that error.
This is already implied by its name (local_err instead of the classic
errp), but it is worth additionally stressing this by adding an
assertion to make it part of the function contract.

The local_err parameter is not here to return information about
nbd_iter_channel_error failure. Instead it's assumed to be filled when
passed to the function. This is already stressed by its name
(local_err, instead of classic errp). Stress it additionally by
assertion.

Markus Armbruster 8cb846db9e crypto: Fix certificate file error handling crash bug
qcrypto_tls_creds_load_cert() passes uninitialized GError *gerr by
reference to g_file_get_contents().  When g_file_get_contents() fails,
it'll try to set a GError.  Unless @gerr is null by dumb luck, this
logs a ERROR_OVERWRITTEN_WARNING warning message and leaves @gerr
unchanged.  qcrypto_tls_creds_load_cert() then dereferences the
uninitialized @gerr.

Fix by initializing @gerr properly.

Markus Armbruster deda497b84 error: Fix -msg timestamp default
-msg parameter "timestamp" defaults to "off" if you don't specify msg,
and to "on" if you do.  Messed up right in commit 5e2ac51917 "add
timestamp to error_report()".  Mostly harmless, because "timestamp" is
the only parameter, so "if you do" is "-msg ''", which nobody does.

Change the default to "off" no matter what.

While there, rename enable_timestamp_msg to error_with_timestamp, and
polish documentation.

Paolo Bonzini e2328a11bd vga: cleanup mapping of VRAM for non-PCI VGA
vga_init_vbe is now used only from ISA VGA cards.  Since the alias is
not needed anymore, remove it (effectively reverting commit 8294a64d7f,
"vga: fix vram double-mapping with -vga std and -M pc-0.12", 2012-05-29)
and the now unused vbe_mapped field of VGACommonState.  The function now
consists of a single memory_region_add_subregion call, so we can inline
it; this avoids incorrect usage from PCI cards.

Thomas Huth 30d2a17b46 hw/i386: Remove the deprecated machines 0.12 up to 0.15
These machines can't be used reliably for migration anymore, quoting
https://lists.gnu.org/archive/html/qemu-devel/2018-12/msg04516.html :

"
 due to the introduction of the memory API, the firmware is not
 migrated correctly from source to destination.  On QEMU <1.3 the
 0xf0000-0xfffff area is basically a copy of the higher
 0xffff0000-0xffffffff area, while on more recent versions it is
 initialized with zeroes and the firmware copies from 0xffff0000 to
 0xf0000.  When you migrate from old to new QEMU, after reboot there's
 nothing at 0xf0000 and bugs ensue.
"

The pc-0.x machines have been marked as deprecated since QEMU v4.0, so
it is time to remove them now.

And while we're at it, mark the remaining pc-1.x machine types
as deprecated now, too, so that we finally only have "pc-i440fx"
and "pc-q35" machine types left (apart from the non-versioned
"isapc" and "microvm") once we remove them in a couple of releases.
