The ongoing QEMU multi-queue block layer effort makes it possible for multiple
threads to process I/O in parallel. The nbd block driver is not compatible with
the multi-queue block layer yet because QIOChannel cannot be used easily from
coroutines running in multiple threads. This series changes the QIOChannel API
to make that possible.

io: check there are no qio_channel_yield() coroutines during
->finalize()
io: follow coroutine AioContext in qio_channel_yield()
