We use meta_workpace_focus_default_window() to sync the input focus back
to a window after it was on shell UI, this is not really necessary on
Wayland, but it is on X11. What this function does internally is ask
MetaWindowStack about the topmost window and focus+raise that window.
In gnome-shell we set the input focus to the default window every time
the key-focus changes to NULL (see shell-global.c ->
sync_stage_window_focus()). Now when closing the alt-tab switcher and
activating a window while there's an always-on-top window on the
workspace, meta_workspace_focus_default_window() will focus that
always-on-top window right after closing the alt-tab switcher, making it
impossible to focus another window using alt-tab.
To fix this, make meta_workspace_focus_default_window() check if there's
an existing focus_window first, if there is, use that, and if there
isn't, resort to just focusing the topmost one.

The ClutterGestureAction base code would correctly try to cancel a
gesture if it would receive GRAB_NOTIFY leave events (that would indicate
other portions of the actor tree stole input away from the gesture actor),
but it would mistakenly do so only if the gesture was already initiated,
possibly leaving stale point information if the gesture collected input
but didn't initiate yet.
This could be indirectly seen clicking with the mouse on OSK keys with
no motions in between, clicks would accumulate on the swipeTracker
gestures until the trigger point, so the third click could drag the
workspaces.
We do always want to unregister the related device/sequence here, do that
while still cancelling any already initiated gesture.

This commit makes the KVM tests run in special VM runners tagged with
the 'kvm' tag. In order to avoid building the kernel image used for
running the tests each pipeline, it's built as part of the CI image
building.
For now, KVM tests are only run on the x86_64 architecture. The reasons
for this are two that the kernel image building script doesn't yet handle
any other architecture than x86_64 due to differences in how the image
is built and handled, as well as the fact that there only exists a kvm
tagged runner for x86_64.

This will allow us to reuse the keys and values more easily, as later
commits will rely on being able to iterate over the keys and values to
construct explict env strings for passing into special test cases.

Previously, we would only check for EXT_swap_buffers_with_damage which
generally will find an implementation. However, some EGL implementations
do not appear to support that naming of the extension, preferring to
only advertise KHR_swap_buffers_with_damage.

We use get_window_for_event() to check whether an event happened on top
of a window or on top of shell UI to decide whether to bypass delivering
the event to Clutter. In case of crossing events though, we can't just
use the device actor to determine whether to forward the event to
Clutter or not: We do want to forward CLUTTER_LEAVE events which
happened on top of shell UI. In that case the device actor is already a
window actor (the pointer already is on top of a window), but the shell
still needs to get the LEAVE crossing event.
Since the event source actor got removed from the detail of
ClutterEvent, the context we're looking for (which actor did the pointer
leave) is now the target actor that the event gets emitted to. Since the
last commit, we also made event filters aware of this context by passing
the target actor to them, so use this context now to determine whether
we're on top of a window or not.

We'll need the additional context of which actor the event will be
emitted to in mutters event filter (see next commit), so pass that
target actor to the event filters that are installed.

Before scanning out the surface of a native client we have
to check the following attributes that influence the
relationship between buffer and the defined result on screen:
- buffer scale
- buffer transform
- viewport
In the future we can loose these checks again in cases where the
display hardware supports the required operations (scaling, cropping
and rotating).

Prior to 67033b0a mutter was accidentally including sizes for
configurations that were just focus state changes. This was not leading
to any known problems on the client side, but it was causing issues in
mutter itself when detecting whether a resize originated from the client
or the server.
Not including sizes in focus change configurations anymore however
revealed a bug in gtk. It was storing the window size when in a fixed
size mode (tiled/maximized/fullscreen), but not on any other server side
resizes. It was then restoring this stored size whenever there was a new
configuration without a size while in floating mode, i.e. the focus
change configurations generated by mutter after 67033b0a.
This change now addresses the issue 67033b0a was fixing in a way that
restores the previous behavior of always including the size whenever
sending a configuration.

and compilation flags, have each of those tests run coverage in order
to generate a JSON report, and have that merged at a final common job.
