sheepdog: use coroutines
This makes the sheepdog block driver support bdrv_co_readv/writev
instead of bdrv_aio_readv/writev.
With this patch, Sheepdog network I/O becomes fully asynchronous. The
block driver yields back when send/recv returns EAGAIN, and is resumed
when the sheepdog network connection is ready for the operation.
