    xf86-video-mga: remove the GlxSetVisualConfigs stub and friends
    
    The function was an empty since 2008 at least. Remove it alongside the
    unused GLX visuals code.
    
    With this all the GL/GLX dependencies in the driver are gone.

    There's a GLX reference in mga_ucode.h - a file which was seemingly
    never used since day 1. I'm not going to bother with that, since I've
    taken enough of a diversion already ;-)
