    hammer2 - Major hammer2_chain_*() API cleanup
    
    * Do a major rewrite of the hammer2_chain_*() API functions, primarily
      dealing with whether the caller wants data instantiated for a chain
      element or not.
    
      Also revamp the locking calls.  Integrate the ref count into
      hammer2_chain_lock() to simplify the operation.
    
    * Add infrastructure to allow a minimum physical I/O size to be specified
      independently from the allocation size.  Not finished yet and currently
      disabled.
    
    * Optimize I/O a little, but this still needs a ton of work.
      Set B_CLUSTEROK for logical buffers.
    
    * Add some statistics gathering.
    
    * Remove several duplicative functions.
