We can change power save mode for two reasons: gsd-power told us to, or
we saw a hotplug event. Sometimes it's useful to be able to make the
distinction to why a power save mode changed, so add a reason to the
signal.

If the deadline timer is disabled (like on nvidia-drm or when
`MUTTER_DEBUG_KMS_THREAD_TYPE=user`), then we need to call
`meta_kms_device_set_needs_flush` on every cursor movement. But some were
getting skipped if they coincided with page flips, which resulted in some
cursor movements failing to schedule the frame clock. This resulted in
unnecessary levels of frame skips when using lower frequency input devices
which are less likely to provide another event within the same frame period.

Add a pair of calls to ensure the error trap infrastructure
survives for the MetaBackend. This will help on later commits that
largely operate on the MetaBackendX11 Display.

Keep a per-display list of error traps, so we don't mix them
together, and possibly deem unintended error traps outdated.
This means init/deinit calls are now stackable, and need to
happen evenly. In order to honor this, move the MetaX11Display
error trap destrution to finalize.

We currently have a bit of a disaster area wrt X11 error handling,
with all of Cogl/Clutter/Mutter offering implementations with different
expectations and different degrees of integration with other error
handlers.
It makes more sense to have a single X11 error handling implementation
that is used in all those places. Mtk seems like the reasonable place
to have this kind of general API, so adopt the more advanced code
at src/x11.

This forces not using the seat_proxy. But still allows the use of
session_proxy.
On tests, headless mode is explicitly set and it might not be available a
systemd session. To avoid test failing on this situation skip using
meta_launcher wich uses session_proxy and seat_proxy.

If we're a input-only remote desktop session, create libei regions on an
absolute pointer device corresponding to all logical monitors. This
allows absolute pointer motions without screen casting.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3228>
Sometimes it makes no sense to have a shared pointer device, for example
when they have no set region occupying the global stage coordinate
space. This applies to for example window screen cast based pointer
device regions - they are always local to the window, and have no
position.
We do need shared absolute devices in some cases though, primarily
multi-head remote desktop, where it must be possible to keep a button
reliably pressed when crossing monitors that have their own
corresponding regions.
To handle this, outsource all this policy to the one who drives the
emulated input devices. Remote desktop sessions where the screen casts
correspond to specific monitors (physical or virtual), we need to make
sure they map to the stage coordinate space, while for window screencast
or area screencasts, we create standalone absolute pointer devices with
a single region each.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3228>
We already have the remote desktop session ID, and we'll soon need the
actual remote desktop session in the screen cast session, so pass it on
construction.
The old screen cast type is set implicitly instead.

A MetaEisViewport represents an absolute region backend by e.g. a
pointer device. There are two kinds: a standalone viewport, which
corresponds to a viewport that has no neighbours, and a non-standalone,
which represents a region of a global coordinate space.
The reason for having non-standalone viewports is to allow to mirror the
logical monitor layout of a desktop, while the standalone are meant to
represent things that are not part of the logical monitor layout.

How EIS will be used depends on its context, meaning we'll have multiple
EIS contexts that expose different things. To prepare for this remove
the global socket since that won't work with multiple contexts.

This used to be the behavior, until commit 5d35138df0 changed the meaning
of the return value of MetaCursorRendererClass::update_cursor(). This
made the user of pure-overlay cursors (singular, MetaWaylandTabletTool)
miss their overlays.
Change the return value, so that it matches the desired behavior of
a backend-less overlay-only cursor renderer.

We react on changes to has_hw_cursor, but always try to inhibit if
there is no cursor sprite. While this looks like a reasonable optimization
with the typical situation of one cursor renderer, it may fall into
inhibiting twice without knowing to unwind, e.g.:
1. has_hw_cursor: TRUE, cursor_sprite: !=NULL -> inhibit
2. has_hw_cursor: FALSE, cursor_sprite: NULL -> inhibit
3. has_hw_cursor: TRUE, cursor_sprite: !=NULL -> uninhibit, but once
And this may also result in the CLUTTER_PAINT_FLAG_NO_CURSORS flag
staying on for Tablet cursors, that (so far) always use overlay paths.
This results in invisible tablet cursors after using the mouse at
least once.

Under strange timings, the GTK frames client may implicitly queue
relayouts that end up disagreeing with the latest frame size as
given by Mutter, this results in GTK calling XResizeWindow, and
Mutter plain out ignoring the resulting XConfigureRequestEvent
received.
This however makes GTK think there's pending resize operations,
so at the next resize it will freeze the window, until enough
resizes happened to thaw it again. This is seen as temporary
loss of frame-sync ness (e.g. frozen frame, and other weird
behavior).
In order to make GTK happy and balanced, reply to this
XConfigureRequest, even if just to ignore it in a more polite
way (we simply re-apply the size Mutter thinks the frame should
have, not GTK), this results in the right amount of
ConfigureNotify received on the frames client side, and the
surface to be thawed more timely, while enforcing the size as
managed by Mutter.

This is meant for compatibility purposes with the shell extensions
avoiding to break a bunch of them in the last minute and we would
