    hammer2 - Optimize indirect block algorithm
    
    * Pack indirect blocks for linear files significantly better.
    
    * First level indirect block for directories reduced to 4KB (32 entries).
    
    * For now make the first level indirect block for directories cover the
      entire hash range for either inodes or directory entries (63 bits).
