        This further improves GDM configuration so that
        now only the GDM daemon parses and manages the
        configuration file.  Most client programs use
        the GET_CONFIG command to access needed data.
        This simplifies the configuration logic and
        puts all configuration parsing in one place
        and gets rid of a lot of global variables that
        were making the code look messy.  This also
        gets rid of several places where gnome_config
        deprecated functions were being used.  I have
        cleaned up the code so that the vicious-extensions
        code is more localized in gui/gdmconfig.[ch].
        Some work is left to do:  gdmflexiserver still
        uses gnome_config functions and gdmconfig should
        use the new functions for reading from the
        configuration file.  Some compile issues fixed
        as highlghted by dma...
