NFS: Add version registering framework
This patch adds in the code to track multiple versions of the NFS protocol. I created default structures for v2, v3 and v4 so that each version can continue to work while I convert them into kernel modules. I also removed the const parameter from the rpc_version array so that I can change it at runtime.
