This patch adds two entries into the fs/KConfig file. The first entry
NFS_V4_SECURITY_LABEL enables security label support for the NFSv4 client while
the second entry NFSD_V4_SECURITY_LABEL enables security labeling support on
the server side.

Here and below we also need some warning abouot the current state of
this: we definitely want to warn any distro that might be tempted to
turn this on by default that there's still a chance of
backwards-incompatible protocol changes.
