When we're running under a polyinstantiated SELinux environment, we'll
likely start with an isolated and empty /tmp, meannig no /tmp/.X11-unix
directory to add things to. To make it possible to still function in
this kind of setup, make sure said directory exists.

Instead of using native backend platform data specifically, store
this info in ClutterMotionEvent. This includes time in usec since
it's just used for motion events, in the future it could make sense
to make these general to all events again, but it could make sense
to make ClutterEvent structs private before.
In order to express that a motion event has relative motion info,
the CLUTTER_EVENT_FLAG_RELATIVE_MOTION event flag has been added
for it.

We had code in both backends that sort of independently associated
sequences to slots. Make both transform slots to sequences the same
way, so they may share the implementation convert those back to slots.
This helper now lives in Clutter API.

We have this as platform-dependent data in the native backend, and
a bunch of fallback code done in place in the evcode users. Stop
making this platform-dependent data, and move it to the relevant
ClutterEvents.
The fallback code for the X11 backend case is about the same, but
now it is done directly by the X11 backend.

The XIOErrorExitHandler expects (Display *, void *) whereas mutter uses
(Display *, MetaX11Display *).
That causes a warning at build time:
warning: passing argument 2 of ‘XSetIOErrorExitHandler’ from
incompatible pointer type [-Wincompatible-pointer-types]
813 | XSetIOErrorExitHandler (xdisplay, x_io_error_exit, display);
Actually, the MetaX11Display is not even used, so we can just use the
expected API and ignore the value.

While browsing sysprof profiling reports, I saw surface-commit taking
significant times sometimes; trace attach too, to see whether such
things are due to e.g. texture uploads.

These use now more of a "pull" model, where they receive update
notifications and the relevant input position is queried, instead
of the coordinates being passed along.
This allows to treat cursor renderers all the same independently
of the device they track. This notifying of position changes should
ideally be more backend-y than core-y, a better location will be
figured out in future commits.

Instead of letting the wayland bits maintain an always-software
cursor renderer, let the cursor renderer be managed by the backend,
and only hook to it (as we do for pointer cursor) in the wayland
bits.
ATM, make the cursor renderer still always-software, although
ideally we should allow moving the HW cursor management between
renderers.

Since we schedule frames for each stage view seperately now, surfaces receive
frame callbacks for each stage view they are visible on.
Only emit frame callbacks for the primary stage view.

For X11 grabs, the pattern matching mechanism would simply ignore
applications which have neither WM_CLASS nor WM_NAME set.
When dealing with an override redirect window however, it is not
uncommon that these window have neither value set as these window are
supposed to be ignored by the window manager.
When the WM_CLASS or the WM_NAME is not set by the client, assume the
value is empty so the pattern matching can allow for these.

Commit 8bdd2aa7 would offset the window position by the difference
between the configured window size and the committed size from the
client to prevent the window from drifting while resizing.
This, however, did not take into account the actual geometry scale, so
when using any scale greater than 1, the window would rapidly drift away
due to that offset.
In order to solve this, we need to make sure we store away the pending
window configuration in the stage coordinate space, in order to not
loose precision. When we then calculate the offset given the result from
the client, it'll use the right scalars, while before, one scalar was in
surface coordinates, while the other in stage coordinates.

The semantics for libinput events are not as expected here. Besides
it's pointless, as those should arrive per-slot in a burst, and we
cancel on the first event.
We can simply use the Clutter event for this.

We want to coalesce multiple touch events into the same wl_touch.frame
event. Instead of poking internals to peek the touch events (and their
slots) coming at us before we handle them, simplify things by queueing
the event at a slightly lower priority than events, so we are ensured
to handle all pending input events before sending the event.
If there's no pending events, we can just send the frame event. As it
doesn't make sense to hold any longer.

Implements the "prior window window geometry dimensions" as described in
the documentation of 'xdg_toplevel' request 'unset_maximized':
"If available and applicable, the compositor will include the window
geometry dimensions the window had prior to being maximized in the
configure event."
and 'unset_fullscreen':
"The compositor may include the previous window geometry dimensions in
the configure event, if applicable."
Fixes https://gitlab.gnome.org/GNOME/mutter/issues/792.
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.

If the MetaX11Display abruptly closed when X11 windows were present,
we would still try to deal with them while freezing/thawing for the
"fade out" animation.
At the bottom of that, the X server may be gone, just try to cope
with it.

The spec states:
```
A sub-surface becomes mapped, when a non-NULL wl_buffer is applied
and the parent surface is mapped. The order of which one happens
first is irrelevant. A sub-surface is hidden if the parent becomes hidden,
or if a NULL wl_buffer is applied. These rules apply recursively
through the tree of surfaces.
```
In the past we relied on Clutter actor behaviour to realize the recursive
part - which then broke in
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/664
when we changed the actor hierachy in regards to subsurfaces.
Explicitly encode the desired behaviour in `MetaWaylandSubsurface`, fixing
the issue and making it future proof.

Mutter sends a proximity-in event before the required tablet tool
resource is properly allocated on the client. This is violating the
Wayland protocol. Because libwayland ignores events for objects it
doesn't know yet, this is not noticeable in most applications. However,
if https://gitlab.freedesktop.org/wayland/wayland/-/issues/176 gets
fixed, these applications would likely crash immediately. Therefore this
PR removes the responsible code which, again, shouldn't have any effect
on client applications as they ignore this event anyway.
Relevant part of the spec:
This event can be received when the tool has moved from one surface to
another, or when the tool has come back into proximity above the
surface.

When we resize a window we send it configure requests with size
suggestion. Some clients, e.g. gnome-terminal will limit its size to a
discrete set given the font size resulting in the size often not being
respected completely, but used as a hint to find a size as large as
possible but not larger than the configured size.
When doing an interactive resize dragging the right or top side of a
window, this caused issues with the configured window size not matching
the one used by the client, as the configured position wouldn't be
correct for the actual size. Fix this by offsetting the position given
the size mismatch offset, making the position again in sync with the
size.

A Meta.WaylandClient() object has a GSubprocessLauncher object
passed externally. Currently this object is kept while the
WaylandClient object exists, but is is only needed until the call
to spawn is made.
This patch frees that GSubprocessLauncher just after that call,
thus freeing those resources.

Wayland clients using buffers without alpha channel are not expected to
set an opaque region. However, we rely on the opaque region for the fast
painting path in `MetaShapedTexture`.
Thus, make sure to always set an opaque region internally in those cases.
For X11 clients, wo do so already.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1463
The Meta.WaylandClient constructor receives a GSubprocessLauncher
as a parameter, and stores it internally. Unfortunately, its
refcount value isn't increased, which results in the object being
released twice.
This patch fixes this bug.
