Patch from Erwann Chenede for raise_or_lower keybinding
* src/display.c, src/common.h: POINT_IN_RECT moved to a common
location, removed from here
(meta_rectangle_intersect): move here and make it public
* src/prefs.c: add raise_or_lower keybinding
* src/stack.c (meta_stack_get_below, meta_stack_get_above): add an
arg to only get windows within the same layer
* src/keybindings.c (handle_raise_or_lower): add handling for a
"raise window if obscured, else lower" keybinding
