1708e50b01 NFSD: Add helper to decode OPEN's open_claim4 argument 
Refactor for clarity.

Note that op_fname is the only instance of an NFSv4 filename stored
in a struct xdr_netobj. Convert it to a u32/char * pair so that the
new nfsd4_decode_filename() helper can be used.

d1c263a031 NFSD: Replace READ* macros in nfsd4_decode_fattr() 
Let's be more careful to avoid overrunning the memory that backs
the bitmap array. This requires updating the synopsis of
nfsd4_decode_fattr().

Bruce points out that a server needs to be careful to return nfs_ok
when a client presents bitmap bits the server doesn't support. This
includes bits in bitmap words the server might not yet support.

The current READ* based implementation is good about that, but that
requirement hasn't been documented.

081d53fe0b NFSD: Change the way the expected length of a fattr4 is checked 
Because the fattr4 is now managed in an xdr_stream, all that is
needed is to store the initial position of the stream before
decoding the attribute list. Then the actual length of the list
is computed using the final stream position, after decoding is
complete.

No behavior change is expected.
