Bug 1013 - Per device grabs are not obeyed in pointer device propagation.

Browse Source 
* clutter/clutter-event.c: (clutter_event_get_device_id): swap
arguments of g_return_val_if_fail around.
* clutter/clutter-event.h: added *device field to crossing events as
well.
* clutter/clutter-main.c: (emit_pointer_event): added a device
argument and check for per device grabs if this device is passed.
(clutter_do_event): pass the device if present for all pointer event
emissions.
(generate_enter_leave_events): copy the device from the motion events
when generating enter/leave events.
