This series is based on BlockJobType enum QAPI series. v6: Address comments from Stefan: [04/06] commit: support commit active layer Fix wording. [05/06] qemu-iotests: update test cases for commit active Drop is_active. Experimental for reviewers: the side by side diff against previous series: http://goo.gl/vgN6mc 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.
