[SHOW] EXPLAIN UPDATE/DELETE, code re-structuring
- Make query plan be re-saved after the first join execution
(saving it after JOIN::cleanup is too late because EXPLAIN output
is currently produced before that)
- Handle QPF allocation/deallocation for edge cases, like unsuccessful
BINLOG command.
- Work around the problem with UNION's direct subselects not being visible.
- Update test results ("Using temporary; Using filesort" are now always printed
last in the Extra column)
- This cset gets rid of memory leaks/crashes. Some result mismatches still remain.
