Fix set_maximized and set_fullscreen for unmapped toplevels

Browse source 
* xdg_toplevel.c (Map): Apply queued window manager state.
(SetMaximized, UnsetMaximized, SetFullscreen, UnsetFullscreen):
Set a flag to apply the state later, upon mapping.  If the state
is already set, just send a configure event in response.
