    hammer2 - recover, improve cpu performance
    
    * Move the inode and indirect block duplication tests out of linear
      lists hanging off the topology structure and into their own hash
      tables.
    
    * Massively improves performance during pass 2 on large filesystems
      with many roots or snapshots present that were becoming cpu-bound
      on list traversals.
