Two queues for high-priority and ordinary messages. Fixes #590. These queues are deliberately made small to avoid buffer bloat problem, there is gonna be another queueing layer above them to compensate for that. The queues are designed to be synchronous in enqueueing, async capabilities are to be added layer above later.
