c37977c87d Fix for bug #6462 "Same request on same data returns different 
results." a.k.a. "Proper cleanup of subqueries is missing for SET and DO
statements". (Version #2 with after-review fixes).

To perform proper cleanup for statements that can contain subqueries 
but don't have main select we must call free_undelaid_joins().

3ae044c24f removed incorrect error message about aggregate functions 
improved mechanisn of detection posibility to be NULL for single row queries
switched off substitution optimisation for single row subqueries in PS due to problem in resolving substituted expressions
(changes to make subselects test working with PS protocol)

e3abcb6b53 A fix and test case for Bug#6088 "FOUND_ROWS returns wrong values for 
prepared statements when LIMIT is used" and post-review comments.
The fix changes the approach we calculate the need for ORDER BY 
in UNION: the previous was not PS friendly, as it damaged SELECT_LEX 
options in case of single select.

6c136f99bf Proposed fix for bug #5003 (subselect with MIN() and LIKE crashes server) 
We have next problem here:
active_index is wrong in the subselect's handler on the second val_int() call.
Optimizer sees that we can use index-read for that kind of condition,
and matching_cond() (sql/opt_sum.cc) doesn't. I suspect, proper solution is
to add appropriate code to the matching_cond() but now just added
missed initialization.
