Subject: [PATCH xserver 02/12] xwayland: Bind to wp_tablet_manager if
available and get its seats
If we're notified about the existence of the wp_tablet_manager interface,
we bind to it so that we can make use of any tablets that are (or later
become) available. For each seat that exists or comes into existance at
a later point, obtain the associated tablet_seat.
