    HAMMER Utility - Refactor the histogram code for mirror-stream.
    
    * Refactor the histogram code.  This code is responsible for breaking
      down a large initial mirroring stream into smaller chunks so the
      transaction id can be synced more often.  This way if the stream
      is interrupted it can be restarted at a more recent point instead
      of having to restart further back (or at the beginning).
    
    * Add -S splitsize (default 100MB) to specify the desired breakdown
      for the histogram.
