lockd: Introduce new-style XDR functions for NLMv4
We'd like to prevent local buffer overflows caused by malicious or
broken servers. New xdr_stream style decoders can do that.
For efficiency, we also want to be able to pass xdr_streams from
call_encode() to all XDR encoding functions, rather than building
an xdr_stream in every XDR encoding function in the kernel.
Same idea as the NLM v3 XDR overhaul.
