[PATCH v6 00/16] add virtio_blk device support to vdpa/ifc

[Andy Pei]

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.

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.
