If the ancestor a window is transient for has already been unmanaged
when the window is activated via meta_window_activate_full while its
transient_for property still points to that ancestor, this will cause
the already unmanaged ancestor to get added to the windows workspace.
This is after the ancestor had its workspace set to NULL when it was
unmanaged, causing this to look like an actual workspace change. Once
the window has been added to the workspace, it will never be removed
again, because the it has already been unmanaged. This confuses things
like the shell window tracker and leads to phantom windows being
considered present for apps that are not even running anymore.

When a test failed, an exception would be raised. This meant that the
mocked service would stay alive, and the test case being run eventually
failing due to a timeout, not the failure itself.
Fix this by catching the exception during the test, ensuring that we
tear down properly, then re-raise the same exception again after having
teared down.
This avoids the dead lock, while still printing the appropriate error
message.

With the introduction of MetaContext, the responsibility for handling
signals was changed to the application (e.g. GNOME Shell) using
libmutter. What wasn't fixed was making the stand-alone mutter do the
equivalent as well. This commit fixes this.

When the native backend is paused we still process the udev events
even though this isn't needed and may just cause unneeded events to be
triggered afterwards.
Since we'll resume with full changes on such event, we can just block
the signal hander when paused and restore it afterwards.
As per this we can cleanup also a bit the device adding signal handling
given that now we don't have to disconnect/reconnect it again.

Resume happens after we may have received various events that we've
ignored, so at this point we need to just emit an hotplug event like if
everything changed so that user settings may be re-applied.

On hotplug events we may get informations about what CRTC or connector
changed a property (and the property itself), so in such case let's just
ignore the changes to the non-affected CRTCs/connectors, and let's read
only the affected one
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1964>
On hotplug events we may receive a "CRTC" or "CONNECTOR" property that
indicates which crtc/connector property ID has changed.
In such case, instead of update data for all the devices, only update the
device containing the relative connector.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1964>
Hotplug events may contain CRTC or CONNECTOR ids to notify a property
change to just one owner, so we need to find its parent device.
Also we may want to update properties directly without having to go through
all the devices, so expose a simple way to find them.

In case we have no devices, after a KMS update (both because they've
all have been removed or because there were none), we may need to behave
differently compared to the case in which nothing changed, so add a more
specific KMS update change type

If only gamma changed on drm CRTC's we don't have to rebuild the whole
monitors, nor to inform the backed about, the only consumer could be the
DBus API, and so we still emit a signal, but nothing else is needed.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1964>
Since we cache already all the KMS parameters we care about let's check at
each device update if anything has really changed and only in such case
emit a resources-changed signal.
In this way we can also filter out the DRM parameters that when changed
don't require a full monitors rebuild.
Examples are the gamma settings or the privacy screen parameters, that
emits an udev "hotplug" event when changed, but we want to register those
only when we handle the changed property.

A client request for maximizing itself should always be handled by mutter
by emitting a configure event with the native maximized resolution,
regardless of the client's own set limits. This also aligns the behavior by
allowing fixed-sized windows to go into fullscreen or maximized state.

These match their alpha counterparts, apart from not setting the
alpha bit. This allows our internal mashinery to more easily
distinguish whether we need a slow alpha-pass during rendering or not.

It works correctly with scanouts, in contrast to
clutter_stage_capture_into. Inspired by
meta_screen_cast_area_stream_src_record_to_buffer.
maybe_paint_cursor_sprite is now unused and thus removed.
v2:
* clutter_stage_paint_to_buffer requires switching to recording from an
idle callback as well. (Jonas Ådahl)
v3:
* Set human readable name for idle source. (Ivan Molodetskikh)

The way wl_seat capabilities work, by notifying clients of capabilities
changes, and clients consequently requesting the relevant interface
objects (pointer, keyboard, touch) is inherently racy.
On quick VT changes for example, capabilities on the seat will be added
and removed, and by the time the client receives the capability change
notification and requests the relevant keyboard, pointer or touch,
another VT switch might have occurred and the wl_pointer, wl_keyboard or
wl_touch already destroyed, leading to a protocol error which kills the
client.
To avoid this, create the objects when requested regardless of the
capabilities.
