    hammer2 - Refactor file unlink w/open descriptor (2)
    
    * Stabilization pass
    
    * Fix various deadlocks.  When dealing with hardlinks lock the common
      parent directory before locking the source/target directories.
      Move cache_rename() outside of internal H2 locks.
    
    * Fix an issue with nlinks counting.
    
    * Remove some debugging.
