      Bug#13724099 1032 BYTE MEMORY LEAK NEW_CACHED_ITEM IN SUBQUERY WITH GROUPING OF OUTER COLUMN
      
      JOIN::cleanup didn't run delete_elements on the group_fileds list.
     @ sql/sql_list.h
        Add bool base_ilist::operator==(const base_list &rhs) const
        Cleanup code which was commented out.
     @ sql/sql_select.cc
        tmp_join->group_fields was emptied without running delete_elements().
        Rewrote the logic for avoiding double-delete on the list.

No bundle (reason: useless for push emails).
