Neil Roberts 268ebb1b18 wayland: Add basic input support 
This copies the basic input support from the Clayland demo compositor.
It adds a basic wl_seat implementation which can convert Clutter mouse
events to Wayland events. For this to work all of the wayland surface
actors need to be made reactive.

The wayland keyboard input focus surface is updated whenever Mutter
sees a FocusIn event so that it will stay in synch with whatever
surface Mutter wants as the focus. Wayland surfaces don't get this
event so for now it will just give them focus whenever they are
clicked as a hack to test the code.
