All the code logic related to the pointer has been moved to its own file. The seat is responsible for the lifetime of its wlr_wl_pointer(s), and assigning them to the relevant wlr_wl_output. The wlr_wl_pointer becomes a simple helper to manager the wlr_pointer associated to the seat's wl_pointer and its lifetime.
