        Adding per-display configuration support to GDM.  Now if user has
        a file named /etc/gdm/custom.conf:<displaynum>, the settings in this
        file will override the /usr/share/gdm/defaults.conf and
        /etc/X11/gdm/custom.conf settings.  Only keys that affect the GUI
        behavior are supported.  These include those in the "gui" and
        "greeter" sections and the security/PamStack key.

        * daemon/gdm.c: Update GET_CONFIG command so it accepts a display
          argument.  It is backwards compatible and will return the per-display
          setting if this is passed in, or the non-display value if not
          passed in.  Fix bug that caused PreFetch key to not just return
          the once as it is supposed to.
        * daemon/gdmconfig.[ch], jui/gdmconfig.c: Updated to support
          per-display configuration.
        * daemon/gdm.h: Updated...
