NLM: Shrink the maximum request size of NLM4 requests
NLM version 4 requests estimate the call and reply header sizes rather conservatively, using the very maximum size allowed in the protocol even though Linux always uses only a small fraction of the allowable space. Reduce the size of caller and lock arguments to conserve RPC buffer space while XDR encoding NLM4 arguments. Add compile-time checks to ensure the hostname string won't overflow NLM protocol maximums.
