Since the CI pipeline now runs `meson dist` which includes a test
for an up-to-date NEWS entry, post-branch/release version bumps
have become unwieldy.
It's still useful to increase the API version right after branching
though, so return to bumping it manually and do so now.

Easily seeing the buildtype and debug status can be quite useful.
Gnome-Shell already has it.
And while on it, add a 'Directories' section for already existing
entries.

I don't think this ever happened to me, but it can't hurt enforcing
that every release has a corresponding NEWS entry.
(The script has been copied from Polari, thus the metainfo support)

Create a test system bus and use it to run all the tests, add a mock
SensorsProxy (via dbusmock template) server that implements the
net.hadess.SensorProxy interface.
To make testing easier, the service is created on request of a proxy for
it, whose lifetime controls the mock service lifetime as well.
This is done using a further mock service that is used to manage the
others, using python-dbusmock to simplify the handling.
Add basic tests for the orientation manager.
As per the usage dbusmock, we're now launching all the tests under such
wrapper, so that local dbus environment won't ever considered, and
there's no risk that it may affect the tests results both locally and in
CI.

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.

Tests that creating and starting a virtual screen cast monitor works,
and that at least one one buffer is processed.
Currently the content of the buffer isn't checked more than it can be
mmap():ed. Only MemFd buffers are tested for for now, as DMA buffers
would need a surfaceless EGL context to check properly.

The 0.3.21 release includes busy buffers, which are a requirement
for us to switch to cogl_framebuffer_flush() in the next commit.
Bump pipewire dependency to 0.3.21, and adjust CI to build it from
the corresponding tag.

Current Xwayland has marked the command line option "-listen" as
deprecated in favor of "-listenfd".
Use the pkg-config variable "have_listenfd" (if available) from Xwayland
to determine if we should use that option, to avoid a deprecation
warning when spawning Xwayland.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1682>
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.

Some GSettings schemas moved from g-s-d to gsettings-desktop-schemas
in g-s-d 40.alpha. 40.alpha.1 didn't include the corresponding
adjustment, so do a quick follow-up release to not abort on startup
with the latest g-s-d release.
I messed up and released 40.alpha at the same time as 3.38.2, when it's
supposed to be in January. In order to re-align with the schedule, change
the upcoming version to 40.alpha2 so we don't have to skip a release and
will be back on track in time of 40.beta.
Xwayland in its main development branch now provides a pkg-config file
which can be used to determine Xwayland installation path and various
options enabled at build time.
Change mutter build system to optionally use that mechanism if
available. If not (as with Xwayland from the current stable branch),
keep the fallback mechanisms (basically search for the Xwayland and parse
its command line options to determine if initfd is available).

If this call is available, we can turn libX11 IO errors (fatal by definition)
into something we can recover from. Try to dispose all X11 resources and close
the display instead, so the compositor can survive the event.

Fedora's mutter is built with --auto-features=enabled which enables
-initfd support. But the current meson code doesn't check whether
-initfd is available in Xwayland, leading to the wayland session not
starting up.
Check for -initfd's availability before enabling it.

Mutter itself is versioned now, so passing the version information
to the plugin is redunant now: The version is already determined by
linking to a particular API version (gnome-shell) or by installing
to a versioned plugin path (external plugins).

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.
Fixes#643https://gitlab.gnome.org/GNOME/mutter/issues/643
`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.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/629
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
https://gitlab.gnome.org/GNOME/mutter/merge_requests/497
We've been using configure_file's `install` property for some time now, but this
has been officially supported and works as expected only since meson 0.50, so,
bump version to avoid warnings and ensure the behavior is the one we want.

Pango functions pango_unichar_direction() and pango_find_base_dir() have been
deprecated in pango 1.44, since these are used mostly clutter and gtk, copy the
code from pango and use fribidi dependency explicitly.
This is the same strategy used by Gtk.
