ocfs2: remove versioning information

The versioning information is confusing for end-users. The numbers are
stuck at 1.5.0 when the tools version have moved to 1.8.2. Remove the
versioning system in the OCFS2 modules and let the kernel version be the
guide to debug issues.

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.)
