Commit 25f416c13d added additional compilation warnings, including
-Werror=return-type. There are several places where this results
in build failures if `g_assert_not_reached()` is disabled at compile
time and the compiler misses a return value.

The order and way include macros were structured was chaotic, with no
real common thread between files. Try to tidy up the mess with some
common scheme, to make things look less messy.
- Stop using CurrentTime, introduce META_CURRENT_TIME
- Use g_get_monotonic_time () instead of relying on an
X server running and making roundtrip to it

And use the old "native" backend for both X11 and Wayland. This will
allow us to share fixes between implementations without having to delve
into the XSync X11 extension code.

Otherwise the ClutterEventFilter will consider these handled, and not
forward these to Clutter. This gets necessary for key handling if we
mean to implement the close dialog with Clutter UI.

Just like we do for buttons, with a few twists. These have 2 directions
mappable to different keycombos, and are affected by the current mode
in their group.

As all the relevant backends are expected to provide
ClutterPadButtonEvents, it makes no sense to split the information,
plus all other event fields are now available and might be needed
in the future.

Let the backend initialize the cursor tracker, and change all call
sites to get the cursor tracker from the backend instead of from the
screen. It wasn't associated with the screen anyway, so the API was
missleading.

And remove the wayland-specific handling. This works for both Wayland and
X11 (provided the compositor receives pad events through a passive grab
there).
https://bugzilla.gnome.org/show_bug.cgi?id=773779
Even without a compositor grab, key events may still be expected to
be processed by the compositor and not applications, for instance
when using ctrl-alt-tab to keynav in the top bar. On X11, focus is
moved to the stage window in that case, so that events are processed
before they are dispatched by the window manager. On wayland, we need
to handle this case ourselves, so make sure to not pass key events to
wayland in that case, and move the key focus back to the stage when
appropriate.

Unsetting it in meta_display_handle_event() will make the pointer
emulation checks fail on TOUCH_END event handlers across clutter
actors, the sequence should still be considered as pointer emulating
at that time.
As we don't have a way to hook this post clutter event handling,
instead unset/reset it lazily on the next pointer emulating TOUCH_BEGIN
event, the checks would already fail on other sequences, even if the
pointer emulating touch ended earlier. The only extra thing we need
to take care about is sequence collision, at which point it's safe to
just unset the stored sequence if its new incarnation isn't flagged/
deemed as pointer emulating.
https://bugzilla.gnome.org/show_bug.cgi?id=756754
They otherwise fall through paths that enable bypass_clutter, this
is necessary so they can be picked by captured-event handlers
along the actor hierarchy.

When running as an X11 compositor we do this for every event we see on
the X event stream. As a wayland compositor we don't go through that
code path but since we see all events we can easily do this on motion
events.
In fact, we don't even need this caching when we're a wayland
compositor since we can always find where the pointer is without a
round trip but we're sharing the current monitor logic with the X
path so let's keep it as is for now.

The set/unset branches of meta_display_update_pointer_emulating_sequence()
have been split and put directly where it makes sense. The pointer emulated
sequence will be updated before processing the CLUTTER_TOUCH_BEGIN, and
after processing the CLUTTER_TOUCH_END, this way the checks on this hold
true during all the sequence lifetime.

We've long used a switch statement on the grab operation to determine
where events should go. The issue with MetaGrabOp is that it's a mixture
of a few different things, including event routing, state management,
and the behavior to choose during operations.
This leads to poorly defined event routing and hard-to-follow logic,
since it's sometimes unclear what should point where, and our utility
methods for determining grab operations apart can be poorly named.
To fix this, establish the concept of a "event route", which describes
where events should be routed to.
Instead of returning a value based on whether or not we handled it, we
have this logic: either we have taken a grab on the window, in which
case we have a grab op and have handled it ourselves, or we did not take
a grab and *need* to replay the event to the window.
Handle this in events.c by checking the grab operation in the same way
that we check the other grab ops.
MetaGestureTracker has been separating the "did I handle an event?" and the
"should the event be filtered out?" questions, merge this and make
handle_event() reply to "should the event be only handled by me?".
If a sequence wasn't accepted yet by the gesture tracker, the event will
go through (eg. not handled exclusively by the gesture tracker) and it'll
still be processed by Clutter, triggering gesture actions, and maybe
changing the sequence into other state.

This function tells the obvious on X11, and implements a similar mechanism
on wayland to determine the "pointer emulating" sequence, or one to stick
with when implementing single-touch behavior.
