        The zzip_closedir function is the equivalent of closedir(3) for a realdir or zipfile.

        The zzip_closedir function is magic - if the given arg-ZZIP_DIR is a real directory, it will call the
       real closedir(3) and then free the wrapping ZZIP_DIR structure. Otherwise it will divert to
       zzip_dir_close which will free the ZZIP_DIR structure.
