[svn-r5951]
Purpose: New API functions Description: Added API functions to return pointer to low-level file handle (H5Fget_vfd_handle and H5FDget_vfd_handle) and related property list setting functions(H5Pset_family_offset and H5Pset_multi_type). Platforms tested: Linux 2.2(eirene), Solaris 2.7(arabica), IRIX64 6.5(modi4)
