This patch set add virtio_blk device support to vdpa/ifc driver.
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.
