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. v7: Check on expected fd num in new vhost msg handler. Sanity check on vhost msg size. Fix typo. Add commit log to help understand code. Remove duplicated code. Add new API to get vDPA device type. v6: Fix some commit log. Add vhost socket in log output to make it more user-friendly. When driver ops fail, just output some log, do not break message handler. Check vhost msg size in msg handler. v5: Fix some coding style issues. v4: Add args "isblk" to vdpa example to specify a block device, fix some Issue in example. Make sure code specify for block device does not affect net device. v3: Fix some compile issues. v2: Fix some coding style issues.
