    hammer2 - cleanup, stabilization pass
    
    * MOVED -> SUBMODIFIED was not being set in the parent chain under some
      circumstances.
    
    * Optimize I/O a bit more, there's no point dirtying a chain for a blockref
      update until all sub-chains are clean (at least for now).
    
    * Additional chain locking around certain tests and propagations.
    
    * Numerous fixes to hammer_chain_flush(), sync, and unmount
    
    * Properly destroy the chains for disconnected inodes when the inodes are
      reclaimed.
    
    * Code cleanup.
