Quoting the spec for `wl_data_device::drop`:
> If the resulting action is "ask", the action will not be considered
> final. The drag-and-drop destination is expected to perform one last
> wl_data_offer.set_actions request, or wl_data_offer.destroy in order
> to cancel the operation.
We did not respect the action choosen by the drop destination when
it called `wl_data_offer::set_actions` after `wl_data_device::drop`
if a user override was still active. This eventually resulted in
a protocol error in `wl_data_offer::finish`, as the current action
could still be `ask`.
Fix this by only allowing a user override to `ask` before `drop` is
called, thus making sure the final `set_actions` preference is
honored.

(cherry picked from commit 33b834c433)
With each wl_ouitput corresponding to a monitor, the logical monitor is
not part of the MetaWaylandOutput anymore.
Previously, send_xdg_output_events() would compare the old logical
monitor against the new one to determine whether the size and/or
position was changed and should be sent along with the xdg_output
events.
But that logic is now defeated as there is no old/new logical monitor
anymore, so the updated size or location would never be sent again.
Xwayland relies on this information to update its X11 clients and its
own internal root size, without this the X11 screen size and XRandR
information would never be updated.
To avoid that issue, always send the xdg_output size and location on
xdg_output events, Xwayland is smart enough to update its X11 clients
with XRandR only when the layout actually change.

meta_keymap_x11_replace_keycode currently reports to the X server
that the key types data is changed when adding a key to the keymap.
It's not changed. The number of key types is the same, and none of
them are modified.
This has two bad side effects:
1) It sends all of the key types data into the request
2) It hits a bug in the X server leading to the request getting
rejected entirely. See:
https://gitlab.freedesktop.org/xorg/xserver/-/merge_requests/761
Furthmore, the changed structure used to report to the X server
that the key types data is changed doesn't actually need to modified
at all in the function. It's already prepped by libX11 with the
correct state for the changes mutter is doing when
XkbChangeTypesOfKey is called.
This commit addresses the above two problems by just removing the
lines causing the issues.

Keys in the reserved keycode list are always added for the first group.
Before the previous commit such keycodes were not found unless that was
the current group. But now that we can also find matching keycodes that
are not directly in the current group, this is not necessary anymore.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1955>
Some keys, such as enter or backspace are only bound to a single group,
even if multiple groups are configured. Because the code was previously
only looking for keysyms in the same group as the current one, no
matching keycodes for these would be found if the current group is not
the first group. This was causing those keys to not work on the X11 OSK.
To fix this use the correct action to convert an out of range group for
that key according to its group_info field.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1955>
This effectively changes meta_keymap_x11_get_entries_for_keyval() to
meta_keymap_x11_get_entry_for_keyval() and moves the check if the
keycode maps to the keyval in the current group there. This simplifies
the code a bit and will allow a followup fix.
As a side effect this now also causes the reserved kecodes to be
searched, if no keycodes were found, rather than just when only ones
matching the wrong groups.

The extra stage update we schedule in `apply_state()` is mainly
needed in two situations:
- a partial update happened only in obscurred or off-screen parts
of a surface
- a surface requests frame callbacks without having done damage,
notably the (in)famous Firefox vsync implementation.
Commit 0330ce1f15 limited the update to cases when the actor
was mapped, breaking it for Firefox in the overview.
Remove the mapped check again and get the stage from the backend,
restoring previous behaviour.

Avoid having laptops suspend or lock as soon as the power cable is
unplugged as the timeout for those actions when on battery are smaller
than the timeouts when on AC.
- laptop is plugged in, and hasn't been used for X minutes
- laptop is unplugged
- the gnome-settings-daemon power plugin sets up its timeouts for
inactivity for the "on battery" case
- those X minutes of inactivity are still counting, and are above
the level of one of the timeouts (say, suspend or lock screen),
mutter fires the timeouts
- gsd-power activates the action associated with the timeout

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

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.

In X11 when we switch to another tty all the the signals are blocked (as
the display fd is not replying back to polling, causing the main loop to
stop), and they are all handled once we switch back to the tty.
This is not a problem for most of external events, but in case of
accelerometer changes, once we reactivate a mutter session we'll get
them all together, causing lots of monitor reconfigurations leading to
black screen for some seconds and most of the times to a wrong
configuration being applied.
To avoid this, batch all these events using an idle to only apply the
last one we got in a loop.
