NFSDv4.2: Add NFS v4.2 support to the NFS server

This enables NFSv4.2 support for the server. To enable this code do the following: echo "+4.2" >/proc/fs/nfsd/versions after the nfsd kernel module is loaded. On its own this does nothing except allow the server to respond to compounds with minorversion set to 2. All the new NFSv4.2 features are optional, so this is perfectly legal.
