[Rémi Bernon (＠rbernon)]

--
  v4: dmsynth: Return DMUS_E_SYNTHNOTCONFIGURED when sink fails to activate.
      dmsynth: Return S_FALSE if IDirectMusicSynth_Activate is no-op.
      dmsynth: Forward IDirectMusicSynth_GetLatencyClock to the sink.
      dmsynth: Implement latency IReferenceClock interface on the sink.
      include: Use IReferenceClock interface from strmif.idl in dmusicc.h.
      dmsynth: Move constructor parameter checks to class factory.
