Surgical changes in sql_select and sql_union code in order to
...
accomodate EXPLAIN properly for all possible variant of UNION's
derived tables etc ...
This also fixes all reported (and unreported) bugs when EXPLAIN is
run on UNION's.
select_describe() now has a very dirty hack to avoid some problems
with transactional tables on table unlocking.
Code speedup is possible. For the moment all that was important was
that all tests are passed.
