[Qemu-devel] [PATCH v3 0/3] qmp: Add "blockdev-backup"

[Fam Zheng <famz@redhat.com>]

v3: Address Eric's comments on documentation.
    Squashed 3/4 into 2/4.

v2: Address Markus' and Eric's comments:
    Fix qapi schema documentation.
    Fix versioning of transactions.
    Improve test case code by dropping inelegnet bool.

The existing drive-backup command accepts a target file path, but that
interface provides little flexibility on the properties of target block device,
compared to what is possible with "blockdev-add", "drive_add" or "-drive".

This is also a building block to allow image fleecing (creating a point in time
snapshot and export with nbd-server-add).

(For symmetry, blockdev-mirror will be added in a separate series.)
