Subject: [PATCH 108/268] job: Move single job finalisation to Job

RH-Author: Kevin Wolf <kwolf@redhat.com>

Patchwork-id: 81070
O-Subject: [RHV-7.6 qemu-kvm-rhev PATCH v2 33/73] job: Move single job finalisation to Job
Bugzilla: 1513543
RH-Acked-by: Jeffrey Cody <jcody@redhat.com>
RH-Acked-by: Max Reitz <mreitz@redhat.com>
RH-Acked-by: Fam Zheng <famz@redhat.com>

This moves the finalisation of a single job from BlockJob to Job.

Some part of this code depends on job transactions, and job transactions
call this code, we introduce some temporary calls from Job functions to
BlockJob ones. This will be fixed once transactions move to Job, too.
