Moved LIMIT warning from vers_set_hist_part() to new call vers_check_limit() at table unlock phase. At that point read_partitions bitmap is already pruned by DML code (see prune_partitions(), find_used_partitions()) so we have to set corresponding bits for working history partition. Also we don't do my_error(ME_WARNING|ME_ERROR_LOG), because at that point it doesn't update warnings number, so command reports 0 warnings (but warning list is still updated). Instead we do push_warning_printf() and sql_print_warning() separately. Under LOCK TABLES external_lock(F_UNLCK) is not executed. There is start_stmt(), but no corresponding "stop_stmt()". So for that mode we call vers_check_limit() directly from close_thread_tables(). Test result has been changed according to new LIMIT and warning printing algorithm. For convenience all LIMIT warnings are marked with "You see warning above ^". TODO MDEV-20345 fixed. Now vers_history_generating() contains fine-grained list of DML-commands that can generate history (and TODO mechanism worked well).
