Record the most recently used allocation group on the allocation context, so
that subsequent allocations can attempt to optimize for contiguousness.
Local alloc especially should benefit from this as the current chain search
tends to let it spew across the disk.

We were storing cluster count on the ocfs2_super structure, but never
actually using it so remove that. Also, we don't want to populate the
uptodate cache with the unlocked block read - it is technically safe as is,
but we should change it for correctness.

Get rid of osb->uuid, osb->proc_sub_dir, and osb->osb_id. Those fields were
unused, or could easily be removed. As a result, we also no longer need
MAX_OSB_ID or ocfs2_globals_lock.

Orphan dir recovery can deadlock with another process in
ocfs2_delete_inode() in some corner cases. Fix this by tracking recovery
state more closely and allowing it to handle inode wipes which might
deadlock.

Semaphore to mutex conversion.
The conversion was generated via scripts, and the result was validated
automatically via a script as well.
