[libvirt] [PATCH 1/9] vz: expand start/stop/... APIs for ACL checks

Fri Jun 24 14:32:30 UTC 2016
The original motivation is to expand API calls like start/stop etc so that
the ACL checks could be added. But this patch has its own befenits.
1. functions like prlsdkStart/Stop use common routine to wait for
job without domain lock. They become more self contained and do
not return intermediate PRL_RESULT.
2. vzDomainManagedSave do not update cache twice.
