Due to the way the MetaGestureTracker processes every touch event, this
will tell as closely to Clutter as possible the current number of touches
happening on the stage.
Even though, this is subject to windowing behavior, on X11, rejected touches
will be soon followed by a XI_TouchEnd event, so the compositor will stop
seeing touch sequences that are still operating on clients. On wayland, touch
sequences are processed by the compositor during all their lifetime, so these
will stay on the MetaGestureTracker with META_SEQUENCE_PENDING_END state, yet
still tracked.

On wayland, touches are initially both handled by the compositor and sent
to clients, proceeding to cancellation on clients only after the compositor
claims the sequence for itself. Implement the cancellation detail through
MetaGestureTracker::state-changed.

The capability flags are determined from the device types of the slave devices
that are currently attached. This also happens whenever a device is added or
removed, so the capabilities are kept up to date, and clients know about these.
On VT switch, all slave devices are temporarily removed, so the cascade of
signals will make the seat end up with capabililities=0 while input is suspended.

Anytime the keymap is changed, either directly, or indirectly through the
keyboard capability being released/initialized, there should be a
notification of the modifiers being changed too.

Otherwise the focus_surface_listener list element becomes stale, and then
mangled if the devices' data is initialized again, and the memory memset().

This doesn't match what Weston does. I don't know of any apps that this
fixes (we don't have any apps that even use non-zero dx/dy, I don't
think), but this is part of a cleanup for window geometry.
This reverts commit 3b85e4b2b9.
This breaks touch support; reverting would break wayland
(is what this patch tried to fix; we should find a better solution
that works on both).
The current GNOME Shell Alt-F2 restart looks very messy and also
provides no indication to the user what is going on. We need to
restart the compositor to switch in and out of stereo mode, so
add a framework for doing this more cleanly:
Additions:
meta_restart(): restarts the compositor with a message
MetaDisplay::show-restart-message: signal the embedding
shell to show a message
MetaDisplay::restart: signal the embedding shell to restart
itself.
meta_is_restart(): indicates whether the current instance is a
restart so we can suppress login animations.
A helper program meta-restart-helper holds the composite overlay
window up during the restart to avoid visual artifacts.

Use connect_after() to accomodate code in GNOME Shell that,
when benchmarking drawing performance, connects to ::after-paint
and calls glFinish(). The timing information from that will be
more accurate if we hold off until that completes before we signal
apps to begin drawing the next frame. If there are no other
connections to ::after-paint, connect() vs. connect_after() doesn't
matter.

When a Wayland window acks our arrangement and we don't really have
anything to modify, we'll pass a sole flag of META_IS_WAYLAND_RESIZE
to meta_window_move_resize_internal using a garbage rect. The existing
code to calculate the new rectangle couldn't really handle this case,
and so the garbage rectangle accidentally got stored. Revamp the flag
checks to be more clear about it.
This fixes the weird positioning issues that sometimes appear when
resizing weston-terminal among others.
We really can't do this unless the backend X server is the same as the
frontend X server, as we pass a frontend XID to the backend, which is
only the case when we're not a Wayland compositor.
