    that introduced engine independent persistent statistics.
    In particular:
    - added an enumeration type for possible values of the system
      variable use_stat_tables
    - renamed KEY::real_rec_per_key to KEY::actual_rec_per_key
    - optimized the collection of statistical data for any primary
      key defined only on one column.
