4437. By Michael Widenius <email address hidden>

Fixed crashing bug when using ONLY_FULL_GROUP_BY in a stored procedure/trigger that is repeatedly executed.
This is MDEV-7601, including it's sub tasks MDEV-7594, MDEV-7555, MDEV-7590, MDEV-7581, MDEV-7589

The problem was that select_lex->non_agg_fields was not properly reset for re-execution and this caused an overwrite of a random memory position.
The fix was move non_agg_fields from select_lext to JOIN, which is properly reset.

MDEV-7356: Subquery gives incorrect results

The bug was in remove_sj_conds(), which is used by sj-materialization strategy.
The check used by the function didn't take into account that the subquery could
have another ("grandchild") subquery which is merged into the child subquery.
In that case, grandchild's IN-expression could be incorrectly removed.

Fixed by using more robust logic in remove_sj_conds.

MDEV-7260: Crash in get_best_combination when executing multi-table UPDATE with nested views

Do not use merge_for_insert for commands which use SELECT because optimizer can't work with such tables.

Fixes which makes multi-delete working with normally merged views.

MDEV-7516 Assertion `!cur_p->event' failed in Gcalc_scan_iterator::arrange_event(int, int).
    When the distance in ST_BUFFER is too far negative the coordinates can run out of the operational
    area. We should just return an empty geometry in this case.
