And I just remembered that we committed Anders new weston_surface
configure vfunc. So we can just set the configure vfunc for the black
surface to a black_surface_configure() no-op function and use that to
determine that it's the black surface. I also think that we now need
a void *private pointer in weston_surface now that we have a function
pointer in there.
