Instead of assuming that all POSIX platforms provide mlockall(),

then os_mlock() will fail -ENOSYS, as it does already on Windows.
This is necessary for Haiku, which does not have mlockall().

GCC supports "#pragma GCC diagnostic" since version 4.6, and
Clang seems to support it, too, since its early versions 3.x.
That means that our minimum required compiler versions all support
this pragma already and we can remove the test from configure and
all the related #ifdefs in the code.

Add a pair of configure options --{enable,disable}-libdaxctl to control
whether QEMU is compiled with libdaxctl [1]. Libdaxctl is a utility
library for managing the device dax subsystem.
QEMU uses mmap(2) to maps vNVDIMM backends and aligns the mapping
address to the page size (getpagesize(2)) by default. However, some
types of backends may require an alignment different than the page
size. The 'align' option is provided to memory-backend-file to allow
users to specify the proper alignment.
For device dax (e.g., /dev/dax0.0), the 'align' option needs to match
the alignment requirement of the device dax, which can be fetched
through the APIs of libdaxctl version 57 or up.
[1] Libdaxctl is a part of ndctl project.
The project's repository is: https://github.com/pmem/ndctl
For more information about libdaxctl APIs, you can refer to the
comments in source code of: pmem/ndctl/daxctl/lib/libdaxctl.c.

This patch adds a flag to enable/disable the SafeStack instrumentation
provided by LLVM.
On enable, make sure that the compiler supports the flags, and that we
are using the proper coroutine implementation (coroutine-ucontext).
On disable, explicitly disable the option if it was enabled by default.
While SafeStack is supported only on Linux, NetBSD, FreeBSD and macOS,
we are not checking for the O.S. since this is already done by LLVM.

On aarch64, gcc 9.3 is generating
qemu/exec.c: In function ‘address_space_translate_iommu’:
qemu/exec.c:431:28: note: parameter passing for argument of type \
‘MemTxAttrs’ {aka ‘struct MemTxAttrs’} changed in GCC 9.1
and many other repetitions. This structure, and the functions
amongst which it is passed, are not part of a QEMU public API.
Therefore we do not care how the compiler passes the argument,
so long as the compiler is self-consistent.
The only portion of QEMU which does have a public api, and so
must have a stable abi, is "qemu/plugin.h". We test this by
forcing -Wpsabi in tests/plugin/Makefile.

GDB's remote protocol requires M-profile cores to use the feature
name 'org.gnu.gdb.arm.m-profile' instead of the 'org.gnu.gdb.arm.core'
feature used for A- and R-profile cores. We weren't doing this, which
meant GDB treated our M-profile cores like A-profile ones. This mostly
doesn't matter, but for instance means that it doesn't correctly
handle backtraces where an M-profile exception frame is involved.
Ship a copy of GDB's arm-m-profile.xml and use it on the M-profile
cores. The integer registers have the same offsets as the
arm-core.xml, but register 25 is the M-profile XPSR rather than the
A-profile CPSR, so we need to update arm_cpu_gdb_read_register() and
arm_cpu_gdb_write_register() to handle XSPR reads and writes.

Currently "cf-core.xml" is sent to GDB when using any m68k flavor. Thing is
it uses the "org.gnu.gdb.coldfire.core" feature name and gdb 8.3 then expects
a coldfire FPU instead of the default m68881 FPU.
This is not OK because the m68881 floats registers are 96 bits wide so it
crashes GDB with the following error message:

PIE is supported on many other hosts besides x86.
The default for non-x86 is now the same as x86: pie is used
if supported, and may be forced via --enable/--disable-pie.
The original commit (40d6444e91) said:
"Non-x86 are not changed, as they require TCG changes"
but I think that's wrong -- there's nothing about PIE that
affects TCG one way or another.

The comment in tcg-runtime-gvec.c about CONFIG_VECTOR16 says that
tcg-op-gvec.c has eliminated size 8 vectors, and only passes on
multiples of 16. This may have been true of the first few operations,
but is not true of all operations.
In particular, multiply, shift by scalar, and compare of 8- and 16-bit
elements are not expanded inline if host vector operations are not
supported.
For an x86_64 host that does not support AVX, this means that we will
fall back to the helper, which will attempt to use SSE instructions,
which will SEGV on an invalid 8-byte aligned memory operation.
This patch simply removes the CONFIG_VECTOR16 code and configuration
without further simplification.

glibc and Linux-provided headers are known to generate macro
redefinition warnings when used together. For example:
<linux/mman.h> and <sys/mman.h> duplicate some macro definitions.
We normally never see those warnings because GCC suppresses
warnings generated by system headers. We carry our own copy of
Linux header files, though, and this makes those warnings not be
suppressed when glibc headers are included before Linux headers
(e.g. if <sys/mman.h> is included before <linux/mman.h>).
Use -isystem instead of -I for linux-headers. This makes the
compiler treat our linux-headers directory the same way it treats
system-provided Linux headers, and suppress warnings generated by
them.

The Simple Authentication and Security Layer (SASL) library
re-defines the struct iovec on Win32 [*]. QEMU also re-defines
it in "qemu/osdep.h". The two definitions then clash on a MinGW
build.
We can avoid the SASL definition by defining STRUCT_IOVEC_DEFINED.
Since QEMU already defines 'struct iovec' if it is missing, add
the definition to vnc_sasl_cflags to avoid SASL re-defining it.

On upgrades the old .so files usually are replaced. But on the other
hand since a qemu process represents a guest instance it is usually kept
around.
That makes late addition of dynamic features e.g. 'hot-attach of a ceph
disk' fail by trying to load a new version of e.f. block-rbd.so into an
old still running qemu binary.
This adds a fallback to also load modules from a versioned directory in the
temporary /var/run path. That way qemu is providing a way for packaging
to store modules of an upgraded qemu package as needed until the next reboot.
An example how that can then be used in packaging can be seen in:

The recent Linux io_uring API has several advantages over ppoll(2) and
epoll(2). Details are given in the source code.
Add an io_uring implementation and make it the default on Linux.
Performance is the same as with epoll(7) but later patches add
optimizations that take advantage of io_uring.
It is necessary to change how aio_set_fd_handler() deals with deleting
AioHandlers since removing monitored file descriptors is asynchronous in
io_uring. fdmon_io_uring_remove() marks the AioHandler deleted and
aio_set_fd_handler() will let it handle deletion in that case.

This adds a new binary qemu-storage-daemon that doesn't yet do more than
some typical initialisation for tools and parsing the basic command
options --version, --help and --trace.
Even though this doesn't add any options yet that create things (like
--object or --blockdev), already document that we're planning to process
them in the order they are given on the command line rather than trying
(and failing, like vl.c) to resolve dependencies between options
automatically.

Currently configure's has_sphinx_build() check simply runs a dummy
sphinx-build and either passes or fails. This means that "no
sphinx-build at all" and "sphinx-build exists but is too old" are
both reported the same way.
Further, we want to assume that all the Python we write is running
with at least Python 3.5; configure checks that for our scripts, but
Sphinx extensions run with whatever Python version sphinx-build
itself is using.
Add a check to our conf.py which makes sphinx-build fail if it would
be running our extensions with an old Python, and handle this
in configure so we can report failure helpfully to the user.
This will mean that configure --enable-docs will fail like this
if the sphinx-build provided is not suitable:
Warning: sphinx-build exists but it is either too old or uses too old a Python version
ERROR: User requested feature docs
configure was not able to find it.
Install texinfo, Perl/perl-podlators and a Python 3 version of python-sphinx
(As usual, the default is to simply not build the docs, as we would
if sphinx-build wasn't present at all.)

The next commit will require a sphinx-build that uses Python 3. On
some systems, sphinx-build is fine, on others you need to use
sphinx-build-3. To keep things working out of the box on both kinds
of systems, try sphinx-build-3, then sphinx-build.

This is a fairly light-weight pull request, but I wanted to send it out to
avoid the Goldfish stuff getting buried as the next PR should contain the H
extension implementation.
As far as this PR goes, it contains:
* The addition of syscon device tree nodes for reboot and poweroff, which
allows Linux to control QEMU without an additional driver. The existing
device was already compatible with the syscon interface.
* A fix to our GDB stub to avoid confusing XLEN and FLEN, specifically useful
for rv32id-based systems.
* A device emulation for the Goldfish RTC device, a simple memory-mapped RTC.
* The addition of the Goldfish RTC device to the RISC-V virt board.
This passes "make check" and boots buildroot for me.
