This allows us one less level of indentation of all the tests. It is not
entirely true, the X11 backend test case script can run without it, but
it isn't valuable enough to run without the native backend being enabled
to complicate building.

Instead of having get_seat_id() handle most cases, and then special
casing another case outside of it, let it handle them all, making all
users just able to call get_seat_id().

Except the X11 backend test, it still needs an X server. Eventually we
can replace it with the equivalent that uses Xwayland, but that needs a
"scaled down" mutter that runs as the host compositor for Xwayland, that
doesn't expose anything on the session bus.

It's constructed as a native backend headless backend, but uses a custom
monitor manager (based on MetaMonitorManagerNative) that creates a fake
monitor. Rendering is unconditionally done with the surfaceless
renderer.
The test devices used now use virtual devices, meaning some changes to
the tests to e.g. not set names, and not dealing with input devices
directly.

This is where the viewports are updated, and so lets move connecting the
signal together with it. It also helps a future change to the test
backend where it creates a custom monitor manager.

Test touch devices are autocleaned up, but if a test case explicitly
needs it to be removed at a certain point, make sure to also clear the
pointer so that it doesn't get removed twice.
Right now it's harmless, but in a later commit it'll expected to only
remove a device once.

`update_secondary_gpu_state_post_swap_buffers` decides what our front
buffer object will be. There is only one answer. So return it as the
function result instead of making the caller figure it out.

It's always equal to `onscreen_native->next_frame` and we can't eliminate
that copy so easily. Removing the parameter removes all ambiguity about
where the next frame will come from.

Starting in mesa 24.1 (good in 24.0.9, bad in 24.1.1), the current
kernel somehow manages to hang our VKMS based tests. Let's update the
kernel so we can bump the CI image without running into those hangs.

When a client wants to lease DRM resources, it will attach the list of
connectors is wants to lease and then submit the request.
Once the request is submitted, destroy the DRM lease request object.

When a new device is connected, register a new global for it.
When a device is gone, remove the global. Upon receiving this event,
the client should destroy any matching wp_drm_lease_device_v1 object.
To destroy a wp_drm_lease_device_v1 object, the client must first
issue a release request. Upon receiving this request, send a released
event and destroy the object.

The manager keeps track of which connectors are leasable in general,
which connectors and resources are already part of a lease, and keeps
track of when leases get revoked.
When leasing out connectors, the required drm resources to drive the
connectors are included in the lease as well.

When a plane is leased, it is assigned to a CRTC which is leased. When
trying to find a primary plane for a modeset, skip the assigned planes
on leased CRTCs to avoid sharing the resources with the leased process.

This allows us to keep track when primary and cursor plane assignments
on a CRTC are unassigned. With this commit, all planes which are
assigned are actually in use and can't be assigned to anything else.
We'll make use of that fact when we search for a leasable primary plane.

The lease_objects function takes connectors, CRTCs and planes which are
turned into a drm lease. The resulting lease can be revoked with
revoke_lease. With list_lessees the currently active leases can be
queried.

With leasing, we will give another client control over connectors but
they also need a CRTC to drive them. Those CRTCs won't be available to
the desktop/monitor-manager.

Add an environment variable (MUTTER_DEBUG_LEASE_CONNECTORS) that allows
set a ":" separated list of connector names as available for lease.
The names of the connectors can be found in "/sys/class/drm".
To illustrate it with an example, the names of the connectors and its
status can be fetched with this command:
$ for p in /sys/class/drm/*/status; do con=${p%/status}; echo -n "${con#*/card?-}: "; cat $p; done
DP-1: disconnected
DP-2: disconnected
DP-3: disconnected
DP-4: disconnected
DP-5: connected
DP-6: connected
DP-7: disconnected
eDP-1: connected
HDMI-A-1: disconnected
And, to set "DP-5" and "DP-6" available for lease, the environment
variable can be set like:
MUTTER_DEBUG_LEASE_CONNECTORS=DP-5:DP-6

This is intended to be used to filter out what connectors will be
available for lease, i.e. non-desktop ones.

When mutter creates a dma-buf buffer for screencasting, the buffers
stride will, among other attributes, also be defined.
However, mutter currently only sets the buffer stride, when actually
recording a frame, but not when adding it.
This behaviour disallows screencast consumers (clients) to already
import the respective buffer (i.e. for Vulkan creating a VkImage for the
dma-buf image), as the stride is not yet communicated to the client.
Since the stride won't change after adding the respective buffer,
directly set the buffer stride, when adding the PipeWire buffer. This
allows screencast consumers (clients) to do optimizations in their
encoding paths.

meta_flush_input() creates and runs a main loop in order to block until the
input thread has flushed all its events. This main loop is created on the
default main context though (NULL is passed to g_main_loop_new()), which
means that while the main loop runs, the default main context is active (aka
stage updates will happen).
This causes an issue with tests, specifically when there already is a stage
update queued before running meta_flush_input(): meta_flush_input() will
(as expected) block until the input thread flushed all its events to the
main thread. But while that is happening, the main thread will be doing the
stage update that was already queued, without the new events (the input
thread is just starting to flush those). Then meta_flush_input() returns,
and in our test we see that the stage has been updated, except it wasn't
updated with the latest events. The test now continues and fails.
To fix the issue, make meta_flush_input() truly blocking, so that it only
flushes the input thread, but doesn't drive the global main context while
waiting for that. After the flushing is finished, tests must now manually
iterate the main context themselves to ensure that a stage update happens.
This breaks a few stacking tests, because "move_cursor_to" and "click" use
meta_flush_input() internally. For those commands we now need to dispatch
a stage update afterwards.

Let the ClutterFrame (or rather MetaFrameNative) own both the scanout
object and the framebuffer object, and let the frame itself live for as
long as it's needed. This allows to place fields that is related to a
single frame together, aiming to help reasoning about the lifetime of
the fields that were previously directly stored in MetaOnscreenNative.
Also take the opportunity to rename "current" to "presenting", to make
it clearer that frame's buffer is what is currently presenting to the
user.

It's possible to destory the xdg_toplevel and xdg_surface which removes
the surface role and then re-use the surface on a new toplevel.
Mutter used to not create new SurfaceActors for the new toplevel which
were then shared between the old and new toplevel. This happens because
the actors can stay around after the wl resource is destroyed (e.g. for
closing effects).
