With a lot of similarities, I re-use part of vdpa/ifc driver. Distinguish the virtio net and blk device by device id, and implement specific features and ops. Add example to vdpa to support virtio_blk device. To support blk device live migration, some modification to vhost lib. Perform dev_conf op only under VHOST_USER_SET_VRING_CALL msg. v2: Fix some coding style issue.
