      MDEV-5675 - Performance: my_hash_sort_bin is called too often · b95c8ce5
      Sergey Vojtovich authored
      Reduced number of my_hash_sort_bin() calls from 4 to 1 per query.
      Reduced number of memory accesses done by my_hash_sort_bin().
      
      Details:
      - let MDL subsystem use pre-calculated hash value for hash
        inserts and deletes
      - let table cache use pre-calculated MDL hash value
      - MDL namespace is excluded from hash value calculation, so that
        hash value can be used by table cache as is
      - hash value for MDL is calculated as resulting hash value + MDL
        namespace
      - extended hash implementation to accept user defined hash function
