Add the necessary bits to nfs4_1.x and remove the duplicate definitions from nfs4.h and the uapi nfs4 header. Regenerate the xdr files. Note that regenerating these files caused conflicts with the definitions of NFS4_VERIFIER_SIZE and NFS4_FHSIZE in include/uapi/linux/nfs4.h. These constants are defined by the RFC, and are not part of the kernel API. They have been removed. Userspace consumers who require those constants should plan to get them from more authoritative sources. The nfsstat4 enum defined in the .x is fed to the xdrgen-generated wire encoder and decoder, which treat every enumerated value as legal on the wire. Do not carry the NFS4ERR_FIRST_FREE sentinel (which is not a protocol error code) into the .x; keeping it would make 10097 a value that could leak onto the wire. Instead base nfsd's internal error codes (NFSERR_EOF and friends) at an impossible nfsstat4 value, as lockd does for its nlm__int__* status codes.
