    sbin/hammer: Add functions for zone statistics
    
    - Add functions to init/cleanup/add/print zone statistics and
      make hammer checkmap's existing zone statistics use these.
    
    - hammer_print_zone_stat() shows something like this. Zones with
      0 blocks doesn't necessary mean it has 0 block in that zone.
      For example checkmap doesn't support zone4 (at this point) so
      the block count is 0, but each volume obviously does have at
      least 1 big-block that belongs to zone4.
