        The zzip_dir_fdopen function is used by the zzip_dir_open and zzip_opendir(2) call. Opens the zip-
       archive as specified with the fd which points to an already openend file. The zzip_dir_fdopen function
       then search and parse the zip's central directory.

        NOTE: refcount is zero, so an _open/_close pair will also delete this _dirhandle

        the zzip_dir_fdopen_ext_io function uses explicit ext and io instead of the internal defaults, setting
       these to zero is equivalent to zzip_dir_fdopen

       zzip_dir_fdopen, zzip_dir_fdopen_ext_io -  fd reopen.
