trx_t::autoinc_locks: Use small_vector<lock_t*,4> in order to avoid any dynamic memory allocation in the most common case (a statement is holding AUTO_INCREMENT locks on at most 4 tables or partitions). lock_cancel_waiting_and_release(): Instead of removing elements from the middle, simply assign nullptr, like lock_table_remove_autoinc_lock(). The added test innodb.auto_increment_lock_mode covers the dynamic memory allocation as well as nondeterministically (occasionally) covers the out-of-order lock release in lock_table_remove_autoinc_lock().
