6e818c8c38 build: Allow disabling xwayland
Mostly moving things around to allow a build without xwayland.
Note that more work might still be needed once the x11 build option
lands as that would allow us to have a proper xwayland only build
without the x server part.

7902fa3f9f core: Make sound player feature optional
Mutter can play sounds in some contexts and also provides an API
for libmutter users to do so using libcanberra internally.

In some specific use cases of Mutter, we would like to not depend
on libcanberra and not have any sound playing feature by default.

The changes keeps the sound player API but make it no-op if the
sound_player feature is disabled to not make it possible to break
a gnome-shell build.

See https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/2270

b50353ba23 Add 'catch' option
The catch option makes test run via 'catch'[1], which will log
backtraces whenever an abort or segmentation fault happens in any of the
subprocesses. The aim is to enable this when running in CI to help
debugging crashes that only tend to happen in CI.

While it's possible to wrap the whole meson command in 'catch', doing so
doesn't cover the KVM tests, so this option is added instead that covers
both cases.

7717383deb meson: Allow to build without gnome-desktop
gnome-desktop is used to retrieve the monitor vendor name which in some
use cases is not needed  as it brings a bunch of gnome-desktop unwanted
dependencies.
The change makes mutter fallback to an "Undefined" vendor name if it is
built without gnome-desktop

226afa24aa xwayland: Use Xwayland auto-terminate feature
When using Xwayland-on-demand (default), if the (experimental) autoclose
features is enabled, we can rely on Xwayland's auto-terminate feature
instead of explicitly killing the Xwayland process.

With it, gone is the mechanism that was added to check the X11 clients
connected and their executable to check whether we can (safely) kill
Xwayland.

b7ea424605 documentation: Generate API references with gi-docgen
gtk-doc support was taken out about six years ago, but never replaced.
Add support for the newer gi-docgen, which should hopefully encourage
both C and GJS users of these libraries to improve the reference.

06eb27d503 tests: Run KMS tests inside a QEMU virtual machine
This commit makes it possible to run test executables in a test
environment constructed of a virtual machine running the Linux kernel
with the virtual KMS driver enabled, and a mocked system environment
using meta-dbus-runner.py/python-dbusmock.

The qemu machine is configured to use 256M of memory, as the default
128M was not enough for the tests to pass.

Using qemu is also only made possible on x86_64; more changes are needed
for it to be runnable on aarch64, so add a warning if it was enabled on
any other architecture.

4a0c86ea4c meson: Add optional libsystemd dependency
To utilize the API provided by libsystemd it would be better to
create a separate HAVE_LIBSYSTEMD configuration option instead of
having to rely on HAVE_NATIVE_BACKEND.

For now this will be utilized for getting the control group of a
MetaWindow.

e5347af000 xwayland: Check X11 clients prior to terminate Xwayland
Currently, mutter checks for the presence of X11 windows to decide
whether or not Xwayland can be terminated, when Xwayland is started on
demand.

Unfortunately, not all X11 clients will map a window all the time, an
X11 client may keep the X11 connection opened after closing all its
windows. In that case, we may terminate Xwayland while there are some
X11 client connected still, and terminating Xwayland will also kill
those X11 clients.

To avoid that issue, check the X11 clients actually connected using the
XRes extension. The XRes extension provides the PID of the (local) X11
clients connected to the Xserver, so we need to match that against the
actual executable names, and compare with a list of known executables
that we can safely ignore, such as ibus-x11 or gsd-xsettings.

We also check against our own executable name, considering that the X11
window manager is also an X11 client connected to the Xserver.

Also, XRes returning the PID of local clients only is not a problem
considering that Xwayland does not listen to remote connections.
However, if the user spawns a client remotely on another system using
ssh tunneling (ssh -X), only clients which actually map a window will
be accounted for.

dfe33897db meson_options: Use libGLESv2.so.2 for COGL_DRIVER=gles2, not libGLESv2.so
The former is present on any system that supports OpenGL|ES 2. The latter
is just provided in developer packages. Since we access the library via
`g_module_open` it's safe to just rely on `libGLESv2.so.2`.

166a464515 wayland: Set up initialization X11 socket
This is used by GDK and the X11 bits, but may also be used for
other initialization services we might need to run along with
Xwayland initialization.

However, as the -initfd argument in Xwayland is a fairly new
feature, add some meson build-time checks so that the feature
is handled transparently while allowing to explicitly set/unset
it.

cogl: Add libsysprof capture based tracing
Add the ability to add tracing instrumentation to the code. When
enabled, trace entries will generate a file with timing information
that will be processable by sysprof for generating visualization of
traces over time.

While enabled by default at compile time, it is possible to disable the
expansion of the macros completely by passing --disable-tracing to
./configure.

Tracing is so far only actually done if actually enabled on explicitly
specified threads.

This will be used by Mutter passing the write end of a pipe, where the
read end is sent to Sysprof itself via the D-Bus method 'Capture()'.

By passing that, we have to detect EPIPE that is sent when Sysprof stops
recording. Fortunately, we already ignore the signal at meta_init(), so
no need to add a custom signal handler.

Add Meson support for installed tests
This is the last remaining feature necessary to achieve
parity with the Autotools build.

A few changes were made to the install locations of the
tests, in order to better acomodate them in Meson:

 * Tests are now installed under a versioned folder (e.g.
   /usr/share/installed-tests/mutter-4)

 * The mutter-cogl.test file is now generated from an .in
   file, instead of a series of $(echo)s from within Makefile.

Notice that those tests need very controlled environments
to run correctly. Mutter installed tests, for example, will
failed when running under a regular session due to D-Bus
failing to acquire the ScreenCast and/or RemoteScreen names.

ef85d1a643 Add meson build support
This commit adds meson build support to mutter. It takes a step away
from the three separate code bases with three different autotools setups
into a single meson build system. There are still places that can be
unified better, for example by removing various "config.h" style files
from cogl and clutter, centralizing debug C flags and other configurable
macros, and similar artifacts that are there only because they were once
separate code bases.

There are some differences between the autotools setup and the new
meson. Here are a few:

The meson setup doesn't generate wrapper scripts for various cogl and
clutter test cases. What these tests did was more or less generate a
tiny script that called an executable with a test name as the argument.
To run particular tests, just run the test executable with the name of
the test as the argument.

The meson setup doesn't install test files anymore. The autotools test
suite was designed towards working with installed tests, but it didn't
really still, and now with meson, it doesn't install anything at all,
but instead makes sure that everything runs with the uninstalled input
files, binaries and libraries when running the test suite. Installable
tests may come later.

Tests from cogl, clutter and mutter are run on 'meson test'. In
autotools, only cogl and clutter tests were run on 'make check'.
