Add a helper function to determine if a seat has a (physical)
touchscreen associated with it.
Currently src/backends/meta-backend.c has a private version of this
(check_has_physical_touchscreen) and further patches in this patch-set
need the same functionality. So add a generic helper for this to
avoid code duplication.

Clutter device events are special events coming from the backend when an
input device is added or removed.
When such events are processed, we should make the seat to handle them by
calling vfunc that can be implemented by each backend and eventually
emitting the appropriate signal.
If a device is removed, we can also safely dispose it, as it can be
considered stale at this point.

Add a method to ClutterSeat that allows peeking the list of input
devices and allow looping through devices a bit faster. The API left is
private so we can make use of peeking the GList internally, but don't
have to expose any details to the outside, which means we'd have to
eventually stick with a GList forever to avoid breaking API.
Since we now have the peek_devices() API internally, we can implement
ClutterSeats public list_devices() API using g_list_copy() on the list
returned by peek_devices().

Add API to ClutterSeat that allows inhibiting the unsetting of the
pointer focus surface. This can be useful for drawing custom cursor
textures like the magnifier of gnome-shell does.
In the future this API should also control unsetting of Clutters
focus-actor, not just the focus surface, that's not really needed right
now since we never unset the focus-actor anyway.

And the corresponding getter. This property returns FALSE by default
and must be overridden by subclasses. This will allow gnome-shell to
hook up specific behavior that should not happen on mouse+keyboard
setups.
