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.

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'.
This protocol supersedes the internal gtk_text_input protocol that
was in place. Functionally it is very similar, with just some more
verbosity in both ways (text_change_cause, .done event), and some
improvements wrt the pre-edit text styling.
One of the current limitations of EGLStreams is that there's no way to
resize a surface consumer without re-creating the entire stream.
Therefore, while resizing, clients will send wl_surface::attach requests
so the compositor can re-create its endpoint of the stream, but no
buffer will be available actually. If we proceed with the rest of the
attach operation we'll be presenting an empty buffer.
In order to fix this, a separate wl_eglstream_controller protocol has
been introduced that clients can use to request a stream re-creation
without overloading wl_surface::attach for that purpose.
This change adds the required logic to create the corresponding
wl_eglstream_controller global interface that clients can bind to.
Whenever a client requests a stream to be created, we just need to
create and realize the new EGLStream buffer. The same buffer resource
will be given at a later time to wl_surface::attach, whenever new
content is made available by the application, so we can proceed to
acquire the stream buffer and update the surface state.

This protocol is limited to Xwayland only and is not visible/usable by
any other client.
Mutter uses the following mechanisms to determine if an X11 client
should be granted a grab:
- is "xwayland-allow-grabs" set?
- if set, is the client blacklisted?
- otherwise, has the client set the X11 window property
_XWAYLAND_MAY_GRAB_KEYBOARD on the window using a client message?
- if not, is it a client white-listed either via the default system
list or the settings "xwayland-grab-access-rules"?

The xdg-output protocol aims at describing outputs in way which is
more in line with the concept of an output on desktop oriented systems.
For now it just features the position and logical size which describe
the output position and size in the global compositor space.
This is however much useful for Xwayland to advertise the output size
and position to X11 clients which need this to configure their surfaces
in the global compositor space as the compositor may apply a different
scale from what is advertised by the output scaling property (to achieve
fractional scaling, for example).
This was added in wayland-protocols 1.10.

This commit adds basic screen casting and remote desktoping
functionalty. This works by exposing two D-Bus API services:
org.gnome.Mutter.ScreenCast and org.gnome.Mutter.RemoteDesktop.
The remote desktop API is used to create remote desktop sessions. For
each session, a D-Bus object is created, and an application can manage
the session by sending messages to the session object. A remote desktop
session the user to emit input events using the D-Bus methods on the
session object. To get framebuffer content, the application should
create an associated screen cast session.
The screen cast API is used to create screen cast sessions. One can so
far either create stand-alone screen cast sessions, or a screen cast
session associated with a remote desktop session. A remote desktop
associated screen cast session is managed by the remote desktop session.
So far only remote desktop managed screen cast sessions are implemented.
Each screen cast session may have one or more streams. A screen cast
stream is a stream of buffers of some part of the compositor content.
So far API exists for creating streams of monitors and windows, but
only monitor streams are implemented.
When a screen cast session is started, the one PipeWire stream is
created for each screen cast stream created for the session. When this
has happened, a PipeWireStreamAdded signal is emitted on the stream
object, passing a unique identifier. The application may use this
identifier to find the associated stream being advertised by the
PipeWire daemon.
The remote desktop and screen cast functionality must be explicitly be
enabled at ./configure time by passing --enable-remote-desktop to
./configure. Doing this will build both screen cast and remote desktop
support.
To actually enable the screen casting and remote desktop, the user must
enable the experimental feature. See
org.gnome.mutter.experimental-features.

In order to minimize the amount of breakage, while at the same time
making it easier to make backward incompatible changes needed to
continue turning libmutter into a capable Wayland compositor, make the
libmutter and friends (libmutter-clutter, libmutter-cogl*) parallel
installable by adding a version number to the name. This changes
various filenames, for example what previously was libmutter.so is now
libmutter-0.so (assuming the version for now is 0), and
libmutter-clutter-1.0.so is now libmutter-clutter-0.so. The pkg-config
filenames and GObject introspection has been renamed to reflect this as
well.
This enables a downstream compositor rely on a specific version of the
libmutter API, while gracefully handling API/ABI changes by having to
update to the new version at their own pace.

This commits adds support for exporting xdg_surface handles via
xdg_exporter and importing them via xdg_importer.
This bumps the required wayland-protocols version to 1.6.

intltool is unmaintained nowadays while upstream gettext gained
support for formats like GSettings schemas and .desktop files,
and offers a mechanism to teach it about other XML formats not
yet supported out of the box which we can use for the rest.
So there's nothing stopping us, just make the switch ...

This protocol is an internal mirror of the primary selection drafts
being proposed for wayland-protocols. No changes besides prefix/suffix
changes.

The wp_pointer_constraints protocol is a protocol which enables clients
to manipulate the behavior of the pointer cursor associated with a seat.
Currently available constraints are locking the pointer to a static
position, and confining the pointer to a given region.
Currently locking is fully implemented, and confining is implemented for
rectangular confinement regions.
What else is lacking is less troublesome semantics for enabling the lock
or confinement; currently the only requirement implemented is that the
window that appears focused is the one that may aquire the lock.
This means that a pointer could be 'stolen' by creating a new window that
receives active focus, or when using focus-follows-mouse, a pointer
passes a window that has requested a lock. This semantics can be changed
and the protocol itself allows any semantics as seems fit.

Add support for sending relative pointer motion deltas to clients who
request such events by creating wp_relative_pointer objects via
wp_relative_pointer_manager.
This currently implements the unstable version 1 from wayland-protocols.

Remove our own copy of the pointer gestures protocol, and us the one
installed by wayland-protocols. This also means the new fixed unstable
naming conventions are used for the new version of the protocol, which
is reflected in the change. No functional changes were made, it is only
a rename.

Add a basic framework for tests of Mutter handling of client behavior;
mutter-test-runner is a Mutter-based compositor that forks off instances
of mutter-test-client and sends commands to them based on scripts.
The scripts also include assertions.
mutter-test-runner always runs in nested-Wayland mode since the separate
copy of Xwayland is helpful in giving a reliably clean X server to
test against.
Initially the commands and assertions are designed to test the stacking
behavior of Mutter, but the framework should be extensible to test other
parts of client behavior like focus.
The tests are installed according to:
https://wiki.gnome.org/Initiatives/GnomeGoals/InstalledTests
if --enable-installed-tests is passed to configure. You can run them
uninstalled with:
cd src && make run-tests
(Not in 'make check' to avoid breaking 'make distcheck' if Mutter can't be
run nested.)

Avoid populating *_VERSION constants through cflags in pkg-config-file
which could be overridden by the project using it. Properly prefix the
defines with META_ to make gi-scanner happy.
This uses David Herrmann's new logind sessions interface to retrieve
fds for input devices, rather than using a custom setuid helper to do
the management. This vastly simplifies the interface.
This requires systemd v210, at least.

Modify all visible instances of mutter with mutter-wayland
