Require the client to have attached (either previously committed, or
newly) a buffer to the corresponding wl_surface, and that the window
will not be potentially mapped until calling wl_surface.commit after
having created the window. This is required to make valid double
buffered xdg_surface state possible when creating a window.
Currently there is no double buffered state in xdg_popup, but it should
behave the same as xdg_surface, and for making it future proof in case
we want to add double buffered state to xdg_popup.
