Long term, we'd like to move to autogenerating a lot of our XDR code.
Both the client and server include include/linux/nfs4.h. That file is
hand-rolled and some of the symbols in it conflict with the
autogenerated symbols from the spec.
Move nfs4_1.x to Documentation/sunrpc/xdr. Create a new
include/linux/sunrpc/xdrgen directory in which we can keep autogenerated
header files. Move the new, generated nfs4xdr_gen.h file to nfs4_1.h in
that directory. Have include/linux/nfs4.h include the newly renamed file
and then remove conflicting definitions from it and nfs_xdr.h.
For now, the .x file from which we're generating the header is fairly
small and just covers the delstid draft, but we can expand that in the
future and just remove conflicting definitions as we go.
