Remove CoglXlibDisplay

Browse Source 
CoglXlibDisplay just contained one member called dummy_xwin. This was
not shared outside of the respective winsys's so I don't think it
really makes sense to have a separate shared struct for it. It seems
more like an implementation detail that is specific to the winsys
because for example it may be that the EGL winsys could use the
surfaceless extension and not bother with a dummy window. This will
also make it easier to factor out the Xlib-specific data in
CoglDisplayEGL to the platform data.
