[PATCH 10/31] NFS: Replace old NFSv3 encoder functions with xdr_stream-based ones

[Chuck Lever <chuck.lever@oracle.com>]

The naming scheme of the new encoder functions, which follows the
NFSv4 XDR encoder functions, is slightly different than the scheme
used for the old functions.  Rename the functions as a separate
step to keep the patches clean.
