It's enabled by default when using the i915 driver, but disabled
everywhere else until it can be made reliably an improvement. Until
then, for anyone want to force-enable it, add the string
'dma-buf-screen-sharing' to the experimental features list in GSettings.

The X server, including Xwayland, can be compiled with different X11
extensions enabled at build time.
When an X11 extension is built in the X server, it's usually also
enabled at run time. Users can chose to disable those extensions at run
time using the X server command line option "-extension".
However, in the case of Xwayland, it is spawned automatically by the
Wayland compositor, and the command line options are not configurable
by users.
Add a new setting to disable a selected set of X extension in Xwayland
at startup, without needing to rebuild Xwayland.
Of course, if Xwayland is not built with a given extension support in
the first place (which is the default for the security extension for
example), that option has no effect.

Make meson link libmutter using -fvisibility=hidden, and introduce META_EXPORT
and META_EXPORT_TEST defines to mark a symbols as visible.
The TEST version is meant to be used to flag symbols that are only used
internally by mutter tests, but that should not be considered public API.
This allows us to be more precise in selecting what is exported and what is
not, without the need of a version-script file that would be more complicated
to maintain.

Make it re-enable:able by a hidden "experimental feature". To enable, add
"kms-modifiers" to the org.gnome.mutter.experimental-features GSettings entry.
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.

Introduce MetaSettings and add the settings managed by MetaBackend into
the new object. These settings include: experimental-features and UI
