Introduce testDomainChgDevice for further development (just like what we
did for IOThread). And introduce testDomainDetachDeviceLiveAndConfig for
detaching devices.
Also as we implement testDomainChgDevice for both DetachDeviceFlags and
DetachDeviceAlias, we could easily implement virDomainDetachDeviceAlias
and virDomainDetachDevice.
