Today virtio-blk dataplane uses a 1:1 device-per-thread model. Now that IOThreads have been introduced we can generalize this to N:M devices per threads. This patch drops thread code from dataplane in favor of running inside an IOThread AioContext. As a bonus we solve the case where a guest keeps submitting I/O requests while dataplane is trying to stop. Previously the dataplane thread would continue to process requests until the request gave it a break. Now we can shut down in bounded time thanks to aio_context_acquire/release.
