Convert wl_input_device to wl_seat (and friends)
wl_input_device has been both renamed and split. wl_seat is now a virtual object representing a group of logically related input devices with related focus. It now only generates one event: to let clients know that it has new capabilities. It takes requests which hand back objects for the wl_pointer, wl_keyboard and wl_touch interfaces it exposes which all provide the old input interface, just under different names. This commit tracks these changes in weston and the clients, as well as similar renames (e.g. weston_input_device -> weston_seat). Some other changes were necessary, e.g. renaming the name for the visible mouse sprite from 'pointer' to 'cursor' so as to not conflict. For simplicity, every seat is always exposed with all three interfaces, although this will change as time goes on. Signed-off-by: Daniel Stone <daniel@fooishbar.org>
