 * Function:    H5Fset_latest_format
 *
 * Purpose:     Enable switching between latest or non-latest format while
 *              a file is open.
 *              This is deprecated starting release 1.10.2 and is modified
 *              to call the private H5F_set_libver_bounds() to set the
 *              bounds.
 *
 *              Before release 1.10.2, the library supports only two
 *              combinations of low/high bounds: 
 *                  (earliest, latest)
 *                  (latest, latest)
 *              Thus, this public routine does the job in switching 
 *              between the two combinations listed above.
 *
 *              Starting release 1.10.2, we add v18 to the enumerated
 *              define H5F_libver_t and the library supports five combinations
 *              as below:
 *                  (earliest, v18)
 *                  (earliest, v10)
 *                  (v18, v18)
 *                  (v18, v10)
 *                  (v10, v10)
 *              So we introduce the new public routine H5Fset_libver_bounds()
 *              in place of H5Fset_latest_format().
 *              See also RFC: Setting Bounds for Object Creation in HDF5 1.10.0.
 *
 * Return:      Non-negative on success/Negative on failure
