Handle subsurfaces with async configure

Browse Source 
With XDG Shell we cannot map a buffer until we get a configure event.
To handle this the normal expose events is blocked then sent explicitly
when we get this request.

This works, but we also need to notify that subsurfaces are now exposed
with the parent.
