Daniel P. Berrange 31cb030ab6 Turn virDomainObjPtr into a virObjectPtr
Switch virDomainObjPtr to use the virObject APIs for reference
counting. The main change is that virObjectUnref does not return
the reference count, merely a bool indicating whether the object
still has any refs left. Checking the return value is also not
mandatory.
