Emmanuele Bassi 73cf6bd52c device: Allow enabling/disabling non-master devices
Slave and floating devices should always be disabled, and not deliver
events to the scene. It is up to the user to enable non-master devices
and handle events coming from them.

ClutterInputDevice gets a new :enabled property, defaulting to FALSE;
when a device manager creates a new device it has to set it to TRUE if
the :device-mode property is set to CLUTTER_INPUT_MODE_MASTER.

The main event queue entry point, _clutter_event_push(), will
automatically discard events coming from disabled devices.
