SUNRPC: Add XDR encoding helper for opaque_auth

Browse source

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.
