Add a flag to MetaSeatNative and MetaSeatImpl that tells it not to
attempt to create a libinput context. This is intended to be used when
mutter is to run headless, as in without any input devices other than
virtual ones.
Currently not hooked up.

With commit c985753442 the support for
multiple hardware cursors broke, but those were never properly supported
anyway as we usually assume there's only one hardware cursor around.
With the introduction of the KMS thread in the future, we'll only have
one KMS cursor that gets updated directly from the input thread. So
apart from the fact that it never really makes sense to have two cursors
visible, in this new model having multiple cursors won't work anyway.
So make the cursor we show for stylii a software cursor again.
Eventually the plan is to make the input device that's driving the KMS
cursor interchangeable, so that we can always use hardware cursors.
This reverts commit 165b7369c8.

We can't post tasks to the input thread when cleaning up the
MetaSeatImpl, as that will make the GTask complain about adding
references to a to be purged object. Avoid this by adding an explicit
meta_seat_impl_destroy() function that handles the destruction of the
MetaSeatImpl properly.
This also does more of the cleanup in the input thread, as that is where
it was managed. Will likely not make a difference as before this
happened after tearing down the thread, but lets tear down things in the
thread they were managed for good measure.
This fixes the last log spew I see right now when terminating mutter.

Instead of using native backend platform data specifically, store
this info in ClutterMotionEvent. This includes time in usec since
it's just used for motion events, in the future it could make sense
to make these general to all events again, but it could make sense
to make ClutterEvent structs private before.
In order to express that a motion event has relative motion info,
the CLUTTER_EVENT_FLAG_RELATIVE_MOTION event flag has been added
for it.

Make it impossible to add individual includes of input thread objects.
This must go through meta-input-thread.h now, which should be enough
to make anyone think it twice.

Simplify the handling of numlock state, so it can be entirely handled
within the input thread. Since the saving/restoring is triggered inside
each backend code, there's no need anymore for meta_backend_set_numlock().

Push it a little bit down to the MetaSeatNative. As both the UI thread
and the input thread are interested in dealing with the xkb_keymap and
it is not meant to be used in different threads, keep 2 separate copies
around.
The keyboard map will always be set from the UI thread, so the xkb_keymap
owned by the MetaSeatNative (owned by the UI thread) can be considered
canonical.

These changes will happen in the input event management code, so let them
be emitted via the MetaSeatImpl, as that's what we'll have neat access to.
The ClutterSeat signals are now emitted from there.

Move most of the functional bits (those meant to run on a standalone
thread) to a MetaSeatImpl object. This object is managed by the MetaSeatImpl
and not exposed outside the friend MetaSeatNative/MetaInputDeviceNative/
MetaInputSettings classes.

We have 2 sources (this one in MetaSeatNative, and the one in
MetaBackend) dispatching ClutterEvents to the stage. Make the
MetaSeatNative one exclusively about dispatching the libinput
queue, and leave ClutterEvents to the other.

This will resort to SW rendering if this cursor renderer does not
own the MetaKmsCursorRenderer, so it's pretty much equivalent thus
far, except we may now implement logic to flip the kms cursor renderer
around.

These use now more of a "pull" model, where they receive update
notifications and the relevant input position is queried, instead
of the coordinates being passed along.
This allows to treat cursor renderers all the same independently
of the device they track. This notifying of position changes should
ideally be more backend-y than core-y, a better location will be
figured out in future commits.

Instead of letting the wayland bits maintain an always-software
cursor renderer, let the cursor renderer be managed by the backend,
and only hook to it (as we do for pointer cursor) in the wayland
bits.
ATM, make the cursor renderer still always-software, although
ideally we should allow moving the HW cursor management between
renderers.

Different devices may get standalone cursor renderers, add this API
to adapt slowly to this. The meta_backend_get_cursor_renderer() call
still exists, but shortcuts to the mouse pointer's renderer (as it
actually did before).

Use a new set in MetaInputDeviceNative, this coexists with
ClutterInputDevice coords for the time being. This API will
eventually be only accessed from the input thread.

xkb recently gained support for user-specified keymaps, which means we
can no longer assume that the configuration data is necessarily fully
complete or correct; and the configuration language is quite a labyrinth,
so it's easy to get wrong. If setting the keymap fails, leave it in
whatever state it previously had, since that seems preferable to crashing
with a NULL pointer dereference.

At startup, libinput dispatch is called from the MetaSeatNative
constructed callback.
That means that we may get libinput events even before the default seat
is set.
In turn, processing those events may trigger the use the default seat
while it's still not set yet, and cause a crash of gnome-shell/mutter
at startup.
A simple reproducer for this is to start gnome-shell/mutter with a
tablet connected and the stylus in proximity, the proximity event will
cause gnome-shell/mutter to crash at startup.
To avoid that issue, avoid dispatching libinput events early from the
MetaSeatNative constructed callback, those events will eventually get
processed when the seat and the backend are all setup.

Rely on the seat stage, or other ways to fetch it. Also rely that
there is actually a single stage, so that we assign the right stage
to all events going out of the seat, in a single place.

This is a bit scattered around, with the setter/getter in Clutter, and
it only being only directly honored in Wayland (it goes straight through
device properties in X11).
Make this private native API, and out of public ClutterInputDevice API.

As it does seem from a read to libinput code, TOUCH_CANCEL events
actually do contain slot information, and are emitted per-slot.
This means we can avoid iterating over the slots ourselves, they
are still expected to be sent altogether.

Add support for the (mostly theoretical) case of an input-device
offering tablet-mode-switch functionality being unplugged.
This makes the has_tablet_switch handling identical to the has_touchscreen
handling, leading to more consistent code.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1506
Detect if a tablet-mode-switch device is already present when mutter
starts by checking for this from meta_seat_native_constructed. This
mirrors how we also set has_touchscreen from meta_seat_native_constructed.
This fixes tablet-mode-switches only being recognized when they are added
at runtime.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1506
Unconditionally setting has_touchscreen to check_touch_mode
when a new device gets added leads to has_touchscreen becoming
false when during runtime e.g. an USB keyboard gets plugged in.
Fix this by setting has_touchscreen to TRUE when check_touch_mode
is TRUE and leaving it alone otherwise.
