Register wl_compositor (+ wl_subcompositor), wl_seat, wl_data_device_manager,
and xdg_wm_base in the compositor's global registry so that Wayland clients
can enumerate and bind them. Add generated xdg-shell-protocol.{h,c} from
wayland-scanner. wl-smoke-test now uses weston-info to verify all three
key globals are present.
