Also add some missing PrintStub calls
* Fix import ordering & Fix incorrect value for the third word in GetDisplayMode
* Add support for events, move concept of domains to IpcService
* Support waiting for KThread, remove some test code, other tweaks
* Use move handle on NIFM since I can't test that now, it's better to leave it how it was
