Up until now all BlockDriverState instances have used the QEMU main loop for fd handlers, timers, and BHs. This is not scalable on SMP guests and hosts so we need to move to a model with multiple event loops on different host CPUs. bdrv_set_aio_context() assigns the AioContext event loop to use for a particular BlockDriverState. It first detaches the entire BlockDriverState graph from the current AioContext and then attaches to the new AioContext. This function will be used by virtio-blk data-plane to assign a BlockDriverState to its IOThread AioContext. Make bdrv_aio_set_context() public since data-plane should not include block_int.h.
