Replace the input_device.attach request with a request for setting a
pointer surface. Also add a new interface, wl_pointer_surface, that
provides a request for setting the hotspot of a pointer surface.
With this change, clients should be able to request frame callbacks
for pointer surfaces in order to implement animated cursors.
