Michael Sevakis e62cb56644 Have voice fire an event when it starts and stops playing.
Further decouples voice_thread.c from other playback areas. Also allows
other audio sources, such as FM radio, to be attenuated when voice is
playing by implementing a callback.

Defined as another playback event rather than a new event class:
PLAYBACK_EVENT_VOICE_PLAYING
