When fixing https://bugzilla.redhat.com/show_bug.cgi?id=1043069 I
realized qemuDomainBlockStats is not the only API that does not acquire
a job early enough. Generally, every API that is going to begin a job
should do that before fetching data from vm->def. The following 5 APIs
failed to do so and moreover used the data fetched early from vm->def
after starting a job. In some circumstances this can lead to a crash.

Jiri Denemark (5):
  qemu: Do not access stale data in virDomainBlockStats
  qemu: Avoid using stale data in virDomainGetBlockInfo
  qemu: Fix job usage in qemuDomainBlockJobImpl
  qemu: Fix job usage in qemuDomainBlockCopy
  qemu: Fix job usage in virDomainGetBlockIoTune
