- Make the code produce correct result: use an array of triggers to turn on/off equalities for each
compared column. Also turn on/off optimizations based on those equalities.
- Make EXPLAIN output show "Full scan on NULL key" for tables for which we switch between
ref/unique_subquery/index_subquery and ALL access.
- index_subquery engine now has HAVING clause when it is needed, and it is
displayed in EXPLAIN EXTENDED
- Fix incorrect presense of "Using index" for index/unique-based subqueries (BUG#22930)

- For row-based IN subqueries, use one flag per each column. Set the flags appropriately before
running the subquery.
sql/item_cmpfunc.h:

BUG#24127: wrong result for (null,not-null) IN (SELECT a,b ...)
- Item_subselect::exec() and subselect_*_engine::exec() don't have parameter
anymore - now Item_subselect owns the pushed down predicates guard flags.
- A correct set of conditional predicates is now pushed into row-based IN
subquery.
- select_indexsubquery_engine now has "HAVING clause" (needed for correct query
results), and it is shown in EXPLAIN EXTENDED
