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.
