        Redesign of daemon configuraton.  Now all vicious-extensions
        logic is in gdmconfig.[ch].  This greatly simplifies how the
        UPDATE_CONFIG, and GET_CONFIG commands work and makes it
        easier to update the way GDM handles configuration.  Changed
        ve_setenv/ve_unsetenv to g_setenv/g_unsetenv since GDM requires
        a newer version of GLIB than could possibly cause the old
        ve versions to get used.

        * daemon/gdmconfig.[ch]: New logic for interacting with
          vicious-extensions.
        * daemon/gdm.h: Updated comments and changed the #define
          for many configuration options so the naming is more
          consistant.  Now the #defines more closely match the
          keys in gdm.conf and more consistantly use the underscore.
        * daemon/auth.c, daemon/choose.c, daemon/cookie.c,
          daemon/display.c, daemon/erro...
