          Fix g_strsplit calls so that NULL return codes are better
          handled.
        * gui/Makefile.am, gui/greeter/Makefile.am, gui/gdmgreeter.[ch],
          Create new gdmgreeter.a library that is only linked by
          gdmlogin and gdmgreeter.  This was needed because I wanted to
          make the gdm_common_is_action_available function a common
          function and the chkauthattr function requires linking additional
          libraries.  This made this change easier and also makes GDM a bit
          cleaner.  It is better, I think, to separate the code only used by
          the greeters since these two programs have more common shared code
          than the other GDM gui programs.
