* Function: H5Fset_latest_format

* Purpose: Enable switching between latest or non-latest format while

* 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
