    HAMMER Util - Add new features, fix history retention bug in prune
    
    * The prune code was not retaining the fine-grained history between
      the last snapshot and current.
    
    * Add a new PFS config variable called 'prune-min' which may be used
      to set the minimum fine-grained history retention, in seconds.  The
      hammer prune code will not prune inbetween any snapshots that are
      within the fine-grained retention period.
    
    * The mirror-stream directive now automatically loops and reconnects
      if the network connection fails.
    
    * The mirror-stream directive now attempts to break-up a large initial
      bulk transfer into smaller transfers, inserting synchronization points
      so a failure in the middle of the large bulk transfer does not require
      starting from scratch again.
    
    * The show directive (show btree) now takes an optional localization[:objid]
      argument (specified in hex).  If specified the directive will search
      the B-Tree for the key, printing nodes as it goes, and then continue
      with a normal iteration.
