convert makefile to be more portable

improve client_from_wlr_surface()

fix compiler error with gcc complaining about parentheses

dwl.c: In function ‘unmaplayersurface’:
dwl.c:2253:9: error: suggest parentheses around assignment used as truth value [-Werror=parentheses]
 2253 |         layersurface->layer_surface->mapped = layersurface->mapped = 0;
      |         ^~~~~~~~~~~~
cc1: all warnings being treated as errors
make: *** [<builtin>: dwl.o] Error 1

clang not affected

disable scene node at unmaplayersurface()

call client_set-size() if client has a resize

check client_surface() returning NULL

now client_surface()->data is a pointer to the wlr_scene_tree of clients
which allows us to not call wlr_scene_node_lower_to_bottom() for every clients

correct libinput function name for drag_lock

destroy layersurface's scene node in destroylayersurfacenotify()

add a new function to get a client from a wlr_surface

Add configuration options for touchpads

implement urgency hints for xwayland clients
