Clean up: Relocate MNT program procedure number definitions to the only file that uses them. Relocate the version number definitions, which are shared, to nfs.h. Remove duplicate program number definitions. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
