This is the counterpart of blockdev-backup. The biggest value of this command
is to allow full flexibility on target image open options, via blockdev-add.
For example this could help solve the target provisioning issue in:

Because mirror job uses bdrv_swap, this series depends on Max's BlockBackend
series:
[PATCH v3 00/38] blockdev: BlockBackend and media
http://lists.nongnu.org/archive/html/qemu-devel/2015-06/msg01109.html
which makes it possible for blockdev-add to insert a BDS without BB (by
omitting "id=" while only specifying "node-name=").
Fam Zheng (6):
block: Add blocker on mirror target
block: Rename BLOCK_OP_TYPE_MIRROR to BLOCK_OP_TYPE_MIRROR_SOURCE
block: Extract blockdev part of qmp_drive_mirror
block: Add check on mirror target
qmp: Add blockdev-mirror command
iotests: Add test cases for blockdev-mirror
