Currently these just use the default (empty) implementations, but they are implemented properly for WMF, so we really need them to be implemented over IPC. The latter two just need to be added to PVideoDecoder and hooked up, should be very easy. IsHardwareAccelerated for WMF looks to be racy at the moment, we're not posting a message to the decoder thread (since it's a sync call) and instead just accessing values from the reader task queue directly. It might be best to return the required values in the InitComplete message on PVideoDecoder, and cache them locally in RemoteVideoDecoder. We might need an extra message for the host to send if these values ever change.

ConfigurationChanged no longer exists.
