SUNRPC: Add XDR encoding helper for opaque_auth
RFC 5531 defines an MSG_ACCEPTED Reply message like this:
struct accepted_reply {
opaque_auth verf;
union switch (accept_stat stat) {
case SUCCESS:
...
In the current server code, struct opaque_auth encoding is open-
coded. Introduce a helper that encodes an opaque_auth data item
within the context of a xdr_stream.
Done as part of hardening the server-side RPC header decoding and
encoding paths.
