v5: Address comments from Eric and Paolo:
Add mirror_start_job and front end wrapper. [Paolo]
Base on BlockJobType enum in QAPI. [Eric]
Drop "common" sync mode. [Eric]
v4: Rewrite to reuse block/mirror.c.
When committing the active layer, the job is internally a mirror job with
type name faked to "commit".
When the job completes, the BDSes are swapped, so the base image become
active and [top, base) dropped.

mirror: don't close target
mirror: move base to MirrorBlockJob
block: add commit_active_start()
commit: support commit active layer
qemu-iotests: update test cases for commit active
commit: remove unused check
