The kernel now supports client-side IPv6 for the main NFS protocols,
but not yet for auxiliary protocols such as NLM.
Enable the text-based mount.nfs logic to resolve hostnames to IPv6
addresses. This should be enough to begin testing the in-kernel NFSv4
support for IPv6.
Since NFSv4 unmounting is only a local process (no communication with the
server) we don't need to do anything to support unmounting an
IPv6-addressed NFSv4 server.
Note that the mount command may now also pass in an IPv6 address via
the "clientaddr=" mount option, though the kernel NFS client doesn't
yet support an IPv6 callback service.
