Add the OPEN4_SHARE_ACCESS_WANT constants from the nfs4.1 and delstid
draft into the nfs4_1.x file, and regenerate the headers and source
files. Do a mass renaming of NFS4_SHARE_WANT_* to
OPEN4_SHARE_ACCESS_WANT_* in the nfsd directory.

Rename the enum with the same name in include/linux/nfs4.h, add the
proper enum to nfs4_1.x and regenerate the headers and source files.  Do
a mass rename of all NFS4_OPEN_DELEGATE_* to OPEN_DELEGATE_* in the nfsd
directory.

In the long run, the NFS development community intends to autogenerate a
lot of the XDR handling code.  Both the NFS client and server include
"include/linux/nfs4.hi". That file was hand-rolled, and some of the symbols
in it conflict with the autogenerated symbols.

Add a small nfs4_1.x to Documentation that currently just has the
necessary definitions for the delstid draft, and generate the relevant
header and source files. Make include/linux/nfs4.h include the generated
include/linux/sunrpc/xdrgen/nfs4_1.h and remove the conflicting
definitions from it and nfs_xdr.h.
