Extensions could previously declare initialisation dependencies on other extensions, which would then get nicely sorted by the loader. We only had one user for this, GLX, which had one pointless (Composite) and one possibly useful dependency (DBE). As DBE is now a built-in, it will always be sorted by GLX, so we no longer have any users for it.
