_sigev_un._tid is an internal glibc field and is not available on
musl libc. The sigevent(7) man page and Linux UAPI headers both use
sigev_notify_thread_id as a public way to access this field.
musl libc supports this field since 1.2.2[0], and glibc plans to
add support as well[1][2].
If sigev_notify_thread_id is not available, fall back to _sigev_un._tid
as before.

The glib version was not previously constrained by RHEL-7 since it
rebases fairly often. Instead SLES 12 and Ubuntu 16.04 were the
constraints in 00f2cfbbec. Both of
these are old enough that they are outside our platform support
matrix now.
Per repology, current shipping versions are:
RHEL-8: 2.56.4
Debian Buster: 2.58.3
openSUSE Leap 15.2: 2.62.6
Ubuntu LTS 18.04: 2.56.4

It has been over two years since RHEL-8 was released, and thus per the
platform build policy, we no longer need to support RHEL-7 as a build
target. So from the RHEL-7 perspective, we do not have to support
libssh v0.7 anymore now.
Let's look at the versions from other distributions and operating
systems - according to repology.org, current shipping versions are:
RHEL-8: 0.9.4
Debian Buster: 0.8.7
openSUSE Leap 15.2: 0.8.7
Ubuntu LTS 18.04: 0.8.0 *
Ubuntu LTS 20.04: 0.9.3
FreeBSD: 0.9.5
Fedora 33: 0.9.5
Fedora 34: 0.9.5
OpenBSD: 0.9.5
macOS HomeBrew: 0.9.5
HaikuPorts: 0.9.5
* The version of libssh in Ubuntu 18.04 claims to be 0.8.0 from the
name of the package, but in reality it is a 0.7 patched up as a
Frankenstein monster with patches from the 0.8 development branch.
This gave us some headaches in the past already and so it never worked
with QEMU. All attempts to get it supported have failed in the past,
patches for QEMU have never been merged and a request to Ubuntu to
fix it in their 18.04 distro has been ignored:
https://bugs.launchpad.net/ubuntu/+source/libssh/+bug/1847514
Thus we really should ignore the libssh in Ubuntu 18.04 in QEMU, too.
Fix it by bumping the minimum libssh version to something that is
greater than 0.8.0 now. Debian Buster and openSUSE Leap have the
oldest version and so 0.8.7 is the new minimum.

We are generating a lot of target-specific defines in the *-config-devices.h
and *-config-target.h files. Using them in common code is wrong and leads
to very subtle bugs since a "#ifdef CONFIG_SOMETHING" is not working there
as expected. To avoid these issues, we are already poisoning many of the
macros in include/exec/poison.h - but it's cumbersome to maintain this
list manually. Thus let's generate an additional list of poisoned macros
automatically from the current config switches - this should give us a
much better test coverage via the different CI configurations.
Note that CONFIG_TCG (which is also defined in config-host.h) and
CONFIG_USER_ONLY are special, so we have to filter these out.

"pkg-config --variable=gdbus_codegen gio-2.0" returns "gdbus-codegen",
and it does not pass test -x (which does not walk the path).
Meson 0.58.0 notices that something is iffy, as the dbus_vmstate1
assignment in tests/qtest/meson.build uses an empty string as the
command, and fails very eloquently:
../tests/qtest/meson.build:92:2: ERROR: No program name specified.
Use the "has" function instead of test -x, and fix the generation
of config-host.mak since meson.build expects that GDBUS_CODEGEN
is absent, rather than empty, if the tool is unavailable.

Clang unfortunately does not support generating code for the z900
architecture level and starts with the z10 instead. Thus to be able
to support compiling with Clang, we have to check for the supported
compiler flags. The disadvantage is of course that the bios image
will only run with z10 guest CPUs upwards (which is what most people
use anyway), so just in case let's also emit a warning in that case
(we will continue to ship firmware images that have been pre-built

Usually Meson uses pre-serialized information in meson-private to
speed up re-runs. This is not possible for version changes, where
Meson instead rebuilds the serialized information using cmd_line.txt.
In some cases cmd_line.txt can contain stale information, since it
is not rebuild except when "meson setup" is invoked. Update it in
the configure script to allow upgrading our Meson version.

Commit "c87ea11631 configure: add --without-default-features" use
default_feature to set default values for configure option. This value
is used for EXESUF too.
However, EXESUF is not option to be tested, it is just append to any
binary name so using --without-default-features set EXESUF to "n"o and
all binaries using it has form <name>no (e.g. qemu-imgno).
This is not expected behavior as disabling features should not cause
generating different binary names.
Reverting back to setting EXESUF to empty value unless needed otherwise.

In bbc17caf81, we used an alias attribute to allow target_page
to be declared const, and yet be initialized late.
This fails when using LTO with several versions of gcc.
The compiler looks through the alias and decides that the const
variable is statically initialized to zero, then propagates that
zero to many uses of the variable.
This can be avoided by compiling one object file with -fno-lto.
In this way, any initializer cannot be seen, and the constant
propagation does not occur.
Since we are certain to have this separate compilation unit, we
can drop the alias attribute as well. We simply have differing
declarations for target_page in different compilation units.
Drop the use of init_target_page, and drop the configure detection
for CONFIG_ATTRIBUTE_ALIAS.
In order to change the compilation flags for a file with meson,
we must use a static_library. This runs into specific_ss, where
we would need to create many static_library instances.
Fix this by splitting page-vary.c: the page-vary-common.c part is
compiled once as a static_library, while the page-vary.c part is
left in specific_ss in order to handle the target-specific value
of TARGET_PAGE_BITS_MIN.

This has the following visible changes:
- GBM is required only for OpenGL dma-buf.
- X11 is explicitly required by gtk-egl.
- EGL is now mandatory for the OpenGL displays.
The last one needs some detailed description. Before this change,
EGL was tested only for OpenGL dma-buf with the check of
EGL_MESA_image_dma_buf_export. However, all of the OpenGL
displays depend on EGL and EGL_MESA_image_dma_buf_export is always
defined by epoxy's EGL interface.
Therefore, it makes more sense to always check the presence of EGL
and say the OpenGL displays are available along with OpenGL dma-buf
if it is present.

Replace the --enable-git-update and --disable-git-update configure params
with the param --with-git-submodules=(update|validate|ignore) to
allow 3 options for building from a git repo.
This is needed because downstream packagers, e.g. Debian, Ubuntu, etc,
also keep the source code in git, but do not want to enable the
'git_update' mode; with the current code, that's not possible even
if the downstream package specifies --disable-git-update.
The previous parameters are deprecated but still available; the
--enable-git-update parameter maps to --with-git-submodules=update and
--disable-git-update parameter maps to --with-git-submodules=validate.
The configure script behavior is slightly modified, where previously
the dtc, capstone, and slirp submodules were not validated when
--disable-git-update was specified (but were updated with git-update
enabled), now they are validated when using --with-git-submodules=validate
and are only ignored when using --with-git-submodules=ignore.

Move the preadv availability check to meson.build. This is what we
want to be doing for host-OS-feature-checks anyway, but it also fixes
a problem with building for macOS with the most recent XCode SDK on a
Catalina host.
On that configuration, 'preadv()' is provided as a weak symbol, so
that programs can be built with optional support for it and make a
runtime availability check to see whether the preadv() they have is a
working one or one which they must not call because it will
runtime-assert. QEMU's configure test passes (unless you're building
with --enable-werror) because the test program using preadv()
compiles, but then QEMU crashes at runtime when preadv() is called,
with errors like:
dyld: lazy symbol binding failed: Symbol not found: _preadv
Referenced from: /Users/pm215/src/qemu/./build/x86/tests/test-replication
Expected in: /usr/lib/libSystem.B.dylib
dyld: Symbol not found: _preadv
Referenced from: /Users/pm215/src/qemu/./build/x86/tests/test-replication
Expected in: /usr/lib/libSystem.B.dylib
Meson's own function availability check has a special case for macOS
which adds '-Wl,-no_weak_imports' to the compiler flags, which forces
the test to require the real function, not the macOS-version-too-old
stub.
So this commit fixes the bug where macOS builds on Catalina currently
require --disable-werror.

There are two cases that need to be accounted for when compiling QEMU
for MinGW32:
1) A standalone distribution, where QEMU is self contained and
extracted by the user, such as a user would download from the QEMU
website. In this case, all the QEMU executable files should be
rooted in $prefix to ensure they can be easily found by the user
2) QEMU integrated into a distribution image/sysroot/SDK and
distributed with other programs. In this case, the provided
arguments for bindir/datadir/etc. should be respected as they for a
Linux build.
Restructures the MinGW path configuration so that all of the paths
except bindir use the same rules as when building for other platforms.
This satisfies #2 and #1 since these files do not need to be directly in
$prefix anyway.
The handling for --bindir is changed so that it defaults to $prefix on
MinGW (maintaining the compatibility with #1), but if the user specifies
a specific path when configuring it can also satisfy #2.

meson.build is already doing the same check, so remove it from
configure.

This patch adds a flag to enable/disable control flow integrity checks
on indirect function calls.
This feature only allows indirect function calls at runtime to functions
with compatible signatures.
This feature is only provided by LLVM/Clang, and depends on link-time
optimization which is currently supported only with LLVM/Clang >= 6.0
We also add an option to enable a debugging version of cfi, with verbose
output in case of a CFI violation.
CFI on indirect function calls does not support calls to functions in
shared libraries (since they were not known at compile time), and such
calls are forbidden. QEMU relies on dlopen/dlsym when using modules,
so we make modules incompatible with CFI.
All the checks are performed in meson.build. configure is only used to
forward the flags to meson

This patch allows to compile QEMU with link-time optimization (LTO).
Compilation with LTO is handled directly by meson. This patch only
adds the option in configure and forwards the request to meson

By default QEMU enables a lot of features if it can probe and find the
support libraries. It also enables a bunch of features by default.
This patch adds the ability to build --without-default-features which
can be paired with a --without-default-devices for a barely functional
build.
The main use case for this is testing our build assumptions and for
minimising the amount of stuff you build if you just want to test a
particular feature on your relatively slow emulated test system. On
it's own I go from:
$ ls -lh qemu-system-aarch64
-rwxr-xr-x 1 alex alex 120M Dec 10 12:45 qemu-system-aarch64*
$ ldd qemu-system-aarch64 | wc -l
170
to:
$ ls -lh qemu-aarch64
-rwxr-xr-x 1 alex alex 43M Dec 10 12:41 qemu-aarch64*
$ ldd qemu-system-aarch64 | wc -l
57
which is still able to run my default Debian ARM64 machine with a lot
less fat involved.

This will allow meson to honour -Dauto_features=disabled later.
