Fixing problems I identified in my auto_increment work pushed in July

(as part of the auto_increment cleanup of WL#3146; let's not be
sad, that monster push still removed serious bugs):
one problem with INSERT DELAYED (unexpected interval releases),
one with stored functions (wrong auto_inc binlogging).
These bugs were not released.
