afs: Implement YFS support in the fs client
Implement support for talking to YFS-variant fileservers in the cache manager and the filesystem client. These implement upgraded services on the same port as their AFS services. YFS fileservers provide expanded capabilities over AFS. Signed-off-by: David Howells <dhowells@redhat.com>
