This series backports patches I did 3 years ago that update the NFS
client's NFSv2 XDR encoders and decoders to use xdr_stream style
marshalling, similar to NFSv4. The immediate advantage is better
bounds checking during marshalling and unmarshalling.
I've already done the kernel's MNT client, lockd's NSM client, and
the kernel's rpcbind client. Eventually, we should convert NFSv3 and
NLM to use this style of marshalling XDR so that we can streamline
call_encode() and call_decode().
