    glx: Fix incorrect use of dri_interface.h version defines in driver probing.
    
    If we extend __DRI_CORE or __DRI_SWRAST in dri_interface.h to allow a
    new version, it shouldn't make old server code retroactively require
    the new version from swrast drivers.
    
    Notably, new Mesa defines __DRI_SWRAST version 4, but we still want to
    be able to probe version 1 drivers, since we don't use any features
    beyond version 1 of the struct.

    glx: Fix incorrect use of dri_interface.h version defines in extensions.
    
    Those defines are so you can compile-time check "do I have a
    dri_interface.h that defines this new field of the struct?"  You don't
    want the server to claim it implements the new struct just because you
    installed a new copy of Mesa.
