Now that cogl understands them, hook wl_shm up so they can be used.
This also bumps the wayland-server version dependency to 1.17.90, which
corresponds to the master branch of wayland. The new formats will be
available in 1.18.0.

GLib will now be linking against sysprof-capture-4.a. To support that,
sysprof had to remove the GLib dependency from sysprof-capture-4 which
had the side-effect of breaking ABi.
This bumps the dependency and includes a fallback to compile just the
libsysprof-capture-4.a using a subproject wrap.

Add MetaAnonymousFile, an abstraction around anonymous read-only files.
Files can be created by calling meta_anonymous_file_new(), passing the
data of the file. Subsequent calls to meta_anonymous_file_open_fd()
return a fd that's ready to be sent over the socket.
When mapmode is META_ANONYMOUS_FILE_MAPMODE_PRIVATE the fd is only
guaranteed to be mmap-able readonly with MAP_PRIVATE but does not
require duplicating the file for each resource when memfd_create is
available. META_ANONYMOUS_FILE_MAPMODE_SHARED may be used when the
client must be able to map the file with MAP_SHARED but it also means
that the file has to be duplicated even when memfd_create is available.

This sets the `is_reactive` flag on the window placement rules, causing
the popups to be reconfigured as they are affected by environmental
changes, such as the parent moving in a way making the popup partially
offscreen.
As with synchronization, the implementation is dormant, as the
version of the advertised global isn't bumped yet, as the new protocol
version is not yet fully implemented.

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.

We want sysprof's exact datadir for compatability with
platforms where software is installed into their own
individual immutable prefix's. Such that, mutter's prefix will
never equate to sysprof's. This depends on a MR in sysprof [0]
which adds datadir to its pkgconfig files, as these files will always
have the proper path we want.
This adds version a constraint on sysprof_dep, as datadir was added to
the .pc in this version.

Without 'wayland/surface-actor: Reset and sync subsurface state when
resetting' this test would fail.
This also adds a simple framework for testing lower level Wayland
semantics.
In contrast to the test-client and test-driver framework, which uses
gtk and tests mostly window management related things, this framework is
aimed to run Wayland clients made to test a particular protocol flow,
thus will likely consist of manual lower level Wayland mechanics.
A private protocol is added in order to help out clients do things they
cannot do by themself. The protocol currently only consists of a request
meant to be used for getting a callback when the actor of a given
surface is eventually destroyed. This is different from the wl_surface
being destroyed due to window destroy animations taking an arbitrary
amount of time. It'll be used by the first test added in the next
commit.

Graphene is a small library with data types and APIs
specially crafted to computer graphics. It contains
performant implementations of matrices, vectors, points
and rotation tools. It is performance because, among
other reasons, it uses vectorized processor commands
to compute various operations.
Add Graphene dependency to Mutter.

GCC's manpage says that this flag does the following:
Do not store floating-point variables in registers, and inhibit other
options that might change whether a floating-point value is taken from
a register or memory.
This option prevents undesirable excess precision on machines such as
the 68000 where the floating registers (of the 68881) keep more
precision than a "double" is supposed to have. Similarly for the x86
architecture. For most programs, the excess precision does only good,
but a few programs rely on the precise definition of IEEE floating
point.
We rely on this behaviour in our fork of clutter. When performing
floating point computations on x86, we are getting the wrong results
because of this architecture's use of the CPU's extended (x87, non-IEEE
confirming) precision by default. If we enable `-ffloat-store` here,
then we'll get the same results everywhere by storing into variables
instead of registers. This does not remove the need to be correct when
handling floats, but it does mean we don't need to be more correct than
the IEEE spec requires.

Since the API version was added, we've bumped it at some point late-ish in
the cycle when enough changes had accumulated (but way after the first ABI
break). Automate that process by computing the API version automatically
from the project version:
With this commit, the new API version will be 5 for the remaining 3.33.x
releases and all 3.34.x stable versions; 3.35.1 will then bump it to 6 and
so forth.

The include <sys/random.h> was added to glibc-2.25, previously was
<linux/random.h>.
Adjust meson build and code to accomodate both.
Fixes: a8984a81c "xwayland: Generate a Xauth file and pass this to
Xwayland when starting it"
https://gitlab.gnome.org/GNOME/mutter/merge_requests/633
Before this commit, sudo x11-app, e.g. sudo gvim /etc/some-file, fails
when running a Wayland session. Where as doing this under a "GNOME on Xorg"
session works fine. For a user switching from the Xorg session to the
Wayland session, this is regression, which we want to avoid.
This commit fixes this by creating and passing an xauth file to Xwayland when
mutter starts it. Just like gdm or startx pass a xauth file to Xorg when they
start Xorg.

`cogl_util_memmem` was used as a wrapper in case `memmem` wasn't
defined, but since commit 46942c24 these are required. In case of
`memmem`, we didn't explicitly require this in the meson build files, so
add that as well.

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 debug flags based on meson's `debug` option instead of `buildtype`.
This allows custom build configurations to behave like a debug or release build.
Add `-fno-omit-frame-pointer` to Mutter/Cogl. Not to Clutter though, as that would
require more changes to how Clutter's gir is created
Remove `-DG_DISABLE_CAST_CHECKS` from Clutter in debug builds
Add `-DG_DISABLE_CHECKS`, `-DG_DISABLE_ASSERT` and `-DG_DISABLE_CAST_CHECKS` to all
non-debug builds but `plain`, which explicitly should not have any compile flags
Use `cc.get_supported_arguments`, so it becomes more obvious to the user which flags
are set during compilation
