          ndb will only allow caching and retrieval if running autocommit
            - return false, but do not invalidate
          commit count is used as engine data, i.e.
            - store commit count before store of cache
            - allow retrieval if commit count has not changed on a table
            - invalidate if commit count has changed

          new virtual handler method cached_table_registration called on each table before alowing store in query cache
            - return TRUE - ok to cache, FALSE - not allowed to cache, invalidate queries if engine_data below has changed
            - sets ulonglong (engine_data) that is stored in query cache for each table
            - sets callback to be called for each table before usage of cached query, callback = 0 -> no check later
      sql/mysql_priv.h
          enabled query cache for ndb
          modified engine interface somewhat
          callcack prototype for callback to engine before query cache retrieval
      sql/sql_cache.cc
          enabled query cache for ndb
          modified engine interface somewhat
          if callback is set on table in cache, do callback to check if allowed to use cache
          if not allowed to use cache, check if engine_data has changed, if so, invalidate all queries with that table
          + changes to store and pass callback and engine_data around

          enabled query cache for ndb
          modified engine interface somewhat
          changes to store callback and engine_data
