ocfs2/net: Add debug interface to o2net
This patch exposes o2net information via debugfs. The information includes
the list of sockets (sock_containers) as well as the list of outstanding
messages (send_tracking). Useful for o2dlm debugging.
(This patch is derived from an earlier one written by Zach Brown that
exposed the same information via /proc.)
