Add a boolean parameter to the signal to inform the handler whether the
timeout completed successfully or not. This allows the shell to
gracefully end the pie timer animation and show a success animation when
the click happens.

When a dwell click causes the pointer to move to another surface, a
synthetic event is generated which triggers another dwell click.
Make sure we ignore those to avoid dwell clicking twice in a raw.

Restarting the dwell click immediately would result in a contant
animation showing.
Start dwell detection in its own timeout handler, which has the nice
effect of not constantly showing a dwell animation and also making sure
that the dwell click timeout is started when pointer movement stops.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/747
Sometimes the dwell timeout doesn't start again after quickly moving the
pointer. That happens if `should_stop_dwell` returns TRUE for the last
motion event we receive: It will stop the current timeout, but not start
a new one until we receive another event where the moved distance is
smaller than the threshold.
To fix this, always call `should_start_dwell` and `start_dwell_timeout`
instead of using an else-block, this makes sure we start a new dwell
timeout still during the same motion event that stopped the old one.

And add the necessary glue so those initialize a X11 clutter backend.
This should get Clutter tests that are dependent on windowing to work
again, thus they were enabled back again.

The end goal is to have all clutter backend code in src/backends. Input
is the larger chunk of it, which is now part of our specific
MutterClutterBackendNative, this extends to device manager, input devices,
tools and keymap.
This was supposed to be nice and incremental, but there's no sane way
to cut this through. As a result of the refactor, a number of private
Clutter functions are now exported for external backends to be possible.

Mutter needs to know which framebuffer the paint nodes will be
drawn into, and using cogl_get_draw_framebuffer() directly is
not an option since ClutterRootNode only pushes the draw fb
at draw time.
Expose clutter_paint_node_get_framebuffer().

Incompressible events already pass through unmodified, so queuing them
just wasted time and memory.
We would however like to keep the ordering of events so we can only
apply this optimization if the queue is empty.
This reduces the input latency of incompressible events like touchpad
scrolling or drawing tablets by up to one frame. It also means the same
series of events now arrives at the client more smoothly and not in
bursts.

Until now we would:
1. Enqueue modifier key event on the stage.
2. Update device modifier state.
3. Dequeue and process modifier key event with NEW device modifier state.
But if we consider optimizing out the queuing in some cases then there
will become a problem:
1. Process modifier key event with OLD device modifier state.
2. Update device modifier state.
To correct the above we now do:
1. Update device modifier state.
2. Queue/process modifier key event with NEW device modifier state.
It appears commit dd940a71 which introduced the old behaviour was correct
in the need to update the device modifier state, but is at least no longer
correct (if it ever was) that it should be done after queuing the event.
If queuing is working, as it is right now, then it makes no difference
whether the device modifier state is updated before or after. Because both
cases will come before the dequeing and processing.

Thanks to the now removed global/context grabs, we can move pointer and
keyboard grabs back home to where they belong.
While at it, also add handling of CLUTTER_TABLET_DEVICE devices to
`on_grab_actor_destroy` and `clutter_input_device_get_grabbed_actor`.

If possible, GLib will try to use the va_marshaller to pass the signal
arguments, rather than unboxing into and out of a `GValue`. This is much
more performant and especially good for often-thrown signals.
The original bug even mentions Clutter performance issues as a drive to
implement the va_marshaller in GLib (see
https://bugzilla.gnome.org/show_bug.cgi?id=661140).
https://gitlab.gnome.org/GNOME/mutter/merge_requests/700
Some of the marshallers we generate in `clutter-marshal.list` are also
available in GLib, so we don't need to generate them ourselves. Even
more, by passing NULL to `g_signal_new` in these cases will actually
internally optimize this even more by also setting the valist
marshaller, which is a little bit faster than the regular marshalling
using `GValue` and libffi.

`g_object_notify()` actually takes a global lock to look up the property
by its name, which means there is a performance hit (albeit tiny) every
time this function is called. For this reason, always try to use
`g_object_notify_by_pspec()` instead.

Since commit 0eab73dc, actors are only allocated when they are actually
visible. While this generally works well, it breaks - because of *course*
it does - ClutterClones when the clone source (or any of its ancestors)
is hidden.
Force an allocation in that case to allow the clone's paint to work as
intended.

The type has been deprecated, so stop using it. The easiest replacement
would be to add our own struct, but considering that separate name/value
arrays are easier to free (g_auto!) and we already do the split in one
place, go that route.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/689
Glib stopped providing any fallback implementations on systems without
memmove() all the way back in 2013. Since then, the symbol is a simple
macro around memmove(); use that function directly now that glib added
a deprecation warning.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/689
Currently nothing in the clutter machinery prevents hidden portions
of the actor tree from calling queue_relayout() (and having it fully
honored).
But that allocation should not be necessary till the actor is shown,
and one of the things we do on show() is queueing a relayout/redraw
after flagging the actor as visible.
We can simply defer clutter_actor_allocate() calls till that show()
call, and leave the needs_allocate and other flags set so we ensure
the allocation is properly set then.
This should cut down some needless operations when invisible portions
of the actor tree change indirectly due to user interaction, or due
to background activity.

Clutter has two motion event toggles: one in the global context, and
one per stage. The global one is deprecated, and currently unused.
Remove the global motion event handling.
