This implements the explicit sync protocol linux-drm-syncobj-v1. This
works by importing a DRM syncobj timeline and importing/exporting fds
to/from the sync points on the timeline corresponding to buffer acquire
and release. We take fds for sync points provided during a surface
commit and use them to delay transaction application, and fetch fds
from Cogl to signal when we are done using a particular buffer.

This adds the explicit sync wayland protocol to the list of build
dependencies.
This adds a copy of the linux-drm-syncobj protocol that we will use
privately for builds. This avoids the pain of requiring wayland-protocols
1.34 for distros. This commit can be reverted once we want to use
linux-drm-syncobj from the system wayland-protocols.

This keeps an internal sync_fd for the latest work submitted to
the GPU. This can then be fetched with cogl_context_get_latest_sync_fd
for use. This is intended for use with linux-drm-syncobj-v1

On big endian architectures the mapping of drm formats to cogl
formats is significantly trimmed compared to on little endian
architectures.
meta_wayland_init_shm tries a bunch of formats, including some
that just aren't mapped on e.g. s390x.
The code asserts the mapping will exist, however, leading to
crashes when Xwayland starts.
This commit makes failure to find a mapping non-fatal.

ClutterInputMethods content hint or purpose will be set again (even to the
same values) whenever a wayland client sends us a new content type/purpose.
Gtk appears to always set a content purpose on wl_text_input changes, so we
currently set and notify the "content-purpose" property on every change in a
gtk text field.
Since the OSK is gnome-shell listens to this property and re-generates its
entire layout when the content-purpose prop gets notified, this is currently
causing lag/freezes on every keypress in the OSK in gnome-shell.
So ensure to not notify these properties in case they're equal and set the
properties in the same way as we usually set them instead of going via
GObject.

When logging in from gdm to gnome, the main plane is deactivated, and
leads to the screen going blank before gnome is able to enable it

Using the new CloseFB ioctl, allows to keep the gdm login screen

When multiple configure requests sent to the wayland client within a sort period, maximized windows may end up in wrong position and cover struts. To avoid this, queue a resize when the resize event sent by the wayland client results a changed size or position to ensure that the final size and position will be always right.

Using `meta_wayland_single_pixel_buffer_from_buffer()` can fail if
the buffer resource is already gone. Given that we release the buffer
immediately, that is actually expected - but the client this was tested
with did/does not do so.
This made the single pixel black bar optimization fail for
GstWaylandsink, while working for the mpv Wayland backend.
Access the object directly, which is both faster and works as long as
the buffer is alive.

Gestures are independent from each other when they are on different
actors and when they don't have a conflict over input with each other: For
example a gesture on one window and a gesture on another window will
recognize at the same time perfectly fine right now.
For those gestures (let's call them "independent gestures") we don't want
to control how the conflicting input should be handled, i.e. whether one
gesture wins over another or whether both can be recognizing using the
same touchpoint (e.g. zoom+rotate on the same actor). Instead we want
to control whether they are allowed to start while another one is running.
For now, make it impossible for two gestures to recognize globally at
the same time in all cases. This helps prevent subtle bugs and makes life
easier for users of the API. We can introduce API for fine grained control
over the behavior later.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2389>
With the next commit, we'll need a list of all gestures that currently are
active globally. Since actors and actions (and therefore also gestures) in
Clutter are bound to a stage, it makes sense for this list to exist on the
ClutterStage level.
The list itself is a simple GPtrArray (to allow for quick searches) that
doesn't reference the gestures and is not manipulated by the stage itself.
All manipulation of the array is left to ClutterGestures.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2389>
Quite often there are situations where multiple gestures try to
recognize, keeping track of the same set of points (for example an edge
drag gesture on the stage and a click gesture somewhere in the
scenegraph). Usually what's wanted here is that the first gesture to
move to RECOGNIZING wins over all other active gestures and "claims" the
point for itself.
We implement this by introducing a concept called "influencing". It
works by making all gestures operating on a shared set of points aware
of each other using ClutterAction->register_sequence().
ClutterGesture uses this vfunc to keep track of all other
ClutterGestures that are potentially conflicting, and keeps a list
(priv->cancel_on_recognizing) of those. As soon as the move to
RECOGNIZING happens, all gestures inside this list get moved to
CANCELLED.
To allow fine-grained control over this behavior, two APIs are
introduced:
1) on the implementation level (should_influence() and
should_be_influenced_by()): This is a vfunc that gets called as soon as
a potential conflict is detected. It's helpful when a specific gesture
always behaves the same towards another gesture, for example to make
sure a LongPress gesture never cancels a DragGesture.
2) on the gesture user level, clutter_gesture_can_not_cancel() is
introduced: This allows control for the user of a gesture to specify
that a specific instance of a gesture won't cancel another gesture.
Calling this twice so that both gestures can't cancel each other allows
for things like simultaneous recognition of a pinch-to-zoom and rotate
gesture.

Introduce ClutterGesture, a new ClutterAction subclass and the successor
of ClutterGestureAction that brings the necessary tools to handle
sequences of events and abstract touch and mouse gestures from those.
The big difference compared to ClutterGestureAction is that ClutterGesture
provides the implementation with point_added/moved/ended and
sequences_cancelled events and expects the implementation to move the
ClutterGesture through the ClutterGestureState state machine. This state
machine is then used internally by ClutterGesture to coordinate with other
gestures.
With the next commits, ClutterGesture will handle relationships between
conflicting gestures completely by itself, allowing the implementation or
the user to specify the details of the relationship between two gestures.

clutter_event_get_source() is still valid for the case of crossing events,
just like clutter_event_get_related(). The latter is not deprecated, so the
former shouldn't be either.

ClutterStage will unref an action in the middle of its own event handler in
case the action causes its own actor to be destroyed. In this case the
action would get freed underneath our feet. To avoid it, take a ref on the
action while calling its handle_event() vfunc, just as we do in
clutter_actor_event() while emitting an event to an actor.

The gnome-shell magnifier listens to the `visibility-changed` signal
and calls meta_cursor_tracker_set_pointer_visible(false) when the
cursor became visible.
This leads to a reentrance in meta_cursor_tracker_set_pointer_visible()
and clutter_seat_uninhibit_unfocus() gets called twice, once from the
meta_cursor_tracker_set_pointer_visible(false) by the magnifier and then
the original meta_cursor_tracker_set_pointer_visible(true) continues,
after the first call has set is_showing to false again. This breaks the
inhibitor counting and the ability to use the cursor while using the
magnifier.

Near window destruction, there might be cases where the surface
actor does no longer have a surface, yet it's still in the stage
and eligible for picking. In that situation looking for modal
dialogs attached to this surface will evidently fail, so avoid
this check on a NULL surface.

Since commit e30eb78891 `ClutterFrameClock` assumes that a valid CPU time
implies timestamp query support, which is also checked in
`cogl_onscreen_egl_swap_buffers_with_damage()`.
Unconditionally setting the CPU time on direct scanout meant that the
compositing path would be stuck on the last (direct scanout optimized)
result on GL implementations without timestamp query support since.

X11 server side focus changes, such as when a focus change was requested
by mutter for a globally active window, did not go through
meta_display_set_input_focus(), which is responsible for emitting the
`focus-window` signal. Since this signal is what triggers the display
server specific code to handle focus changes, this was leading to a
problem on Wayland where the focus remained on the last active Wayland
window when the focus got changed to a globally active XWayland window.
This commit now changes handling X11 server side focus changes to also
go through the code path that emits the signal while making sure to not
trigger another focus change and keeping the same serials as the
previous code to not interfere with future focus changes.

MetaSelectionSourceMemory currently uses GBytes for its underlying data.
This can cause memory overhead when large items, such as HD images, are
stored in the clipboard. This commit changes the underlying data
structure to a MetaAnonymousFile object, which writes to memfd instead
of heap. When reading, MetaSelectionSourceMemory will create a
Gio.UnixInputStream from the file descriptor generated by
MetaAnonymousFile. We subclass the UnixInputStream as
MetaUnixInputStream, to override the stream's close_fn function so
that it invokes meta_anonymous_file_close_fd when the stream terminates.
