This implements the DIRLAYOUTHASH protocol feature, which passes the dir layout over the wire from the MDS. This gives the client knowledge of the correct hash function to use for mapping dentries among dir fragments. Note that if this feature is _not_ present on the client but is on the MDS, the client may misdirect requests. This will result in a forward and degrade performance. It may also result in inaccurate NFS filehandle generation, which will prevent fh resolution when the inode is not present in the client cache and the parent directories have been fragmented.
