Jonas Ådahl 6e7057426e wayland/pointer: Add way to cancel current grab
Previously a grab could suddenly end without the grabber knowing
anything about it. Some grabs assume they won't suddenly end without
notice, and can use then new 'cancel' vfunc to be notified.

Currently a grab is cancelled when a new one is started (i.e. in
meta_wayland_pointer_grab_start()), when a non-popup compositor wide
event route is initiated, and when the seat looses the pointer
capability.
