We currently have a bit of a disaster area wrt X11 error handling,
with all of Cogl/Clutter/Mutter offering implementations with different
expectations and different degrees of integration with other error
handlers.

It makes more sense to have a single X11 error handling implementation
that is used in all those places. Mtk seems like the reasonable place
to have this kind of general API, so adopt the more advanced code
at src/x11.
