exportfs: add new methods
Add the guts for the new filesystem API to exportfs. There's now a fh_to_dentry method that returns a dentry for the object looked for given a filehandle fragment, and a fh_to_parent operation that returns the dentry for the encoded parent directory in case the file handle contains it. There are default implementations for these methods that only take a callback for an nfs-enhanced iget variant and implement the rest of the semantics.
