…operations like SetDB and Prepare. The processlist maintains a Process struct for a given mysql.Conn, and registers a context.CancelFunc for the running operation when the handler dispatches it. This works for queries today. This PR makes it so we also register CancelFunc callbacks for operations which touch the database but do not put the connection into CommandQuery, such as Prepare and ComInit.
