          MDEV-7061: Augment innochecksum to give insight of fragmentation

          Merged https://github.com/facebook/mysql-5.6/commit/615dd07d900ce08948340b6c
          11e37fd1d2a91065 from https://github.com/facebook/mysql-5.6/
          authored by rongrong. Removed C++11 requirement by using
          std::map instead of std::unordered_set.

          Add analysis to leaf pages to estimate how fragmented an index is
          and how much benefit we can get out of defragmentation.
