[Ocfs2-tools-devel] Tools fixes

[Sunil Mushran]

Mostly straight forward patches. Have been tested for sometime now.

[PATCH 1/8] o2cb: Handle failure to register heartbeat mode
This patch was changed as per Joel's recommendation.

[PATCH 2/8] o2cb: Add verbose tracing to o2cb register cluster
[PATCH 3/8] o2cbtool: Disable signals when starting heartbeat
[PATCH 4/8] mounted.ocfs2: Quick detect mode made more efficient
[PATCH 6/8] o2cbtool: Silence usage in list-clusters
These are straight-forward.

[PATCH 5/8] mount.ocfs2: Fix bugs related to hard-ro mounts
I have moved the hard-ro detect code to libocfs2, ocfs2_open().  If found,
fs->fs_flags has the OCFS2_FLAG_HARD_RO flag set.

[PATCH 7/8] debugfs.ocfs2: fs_locks command understands version 3 locking_state format
The new format was pushed to mainline in 2.6.39.

[PATCH 8/8] o2cb.init: Start/stop o2hbmonitor
Only affects the o2cb stack.
