Update the encoder function name to match the type name, as is the
convention with other such encoder utility functions, and with
nfsd4_decode_stateid4().
Make the @stateid argument a const so that callers of
nfsd4_encode_stateid4() in the future can be passed const pointers
to structures.
Since the compiler is allowed to add padding to structs, use the
wire (spec-defined) size when reserving buffer space.

The fattr4 encoder is now structured like the COMPOUND op encoder:
one function for each individual attribute, called by bit number.
Benefits include:
- The individual attributes are now guaranteed to be encoded in
bitmask order into the send buffer
- There can be no unwanted side effects between attribute encoders
- The code now clearly documents which attributes are /not/
implemented on this server

I'd like to convert nfsd4_encode_fattr() to rotate through the
attrmask using for_each_bit() instead of explicitly testing the
bitmask for each bit value. This means I need the bit numbers, as
defined in the specs, instead of our internal bitmask constants.
As a clean up, use the new spec-derived values to define the WORD#
bitmask constants.
