2016-08-19SCI32: Implement kRobotColin Snover
2016-08-06SCI32: Remove VMD flags from Audio32 mixerColin Snover
The VMD decoder sends audio directly to the system mixer.

2016-07-01SCI32: Use better audio fading algorithmColin Snover
Using the one from SCI2.1mid makes fades very slow because SDL has a larger audio buffer than SSCI DOS. This new algorithm is based on wall time so will always fade at the correct speed, although the larger buffers will have a coarser granularity so the fades may not be as smooth as in the original engine. If anyone cares, the fade volume could be mixed into individual samples in `readBuffer` instead of applying just once per complete buffer. SSCI did not do this, however, so this implementation should be pretty accurate.
2016-06-26SCI32: Fix race condition when freeing audio resourcesColin Snover
It's not possible to call any ResourceManager methods from any thread other than the main thread because it is not thread-safe.

2016-06-20SCI32: Rewrite digital audio engineColin Snover
This provides a complete implementation of kDoAudio through SCI2.1mid, plus partial implementation of SCI3 features. Digital audio calls shunted through kDoSound have also been updated to go through the SCI32 audio mixer, though these shunts are a bit hacky because the ScummVM implementation of kDoSound does not currently match how SSCI kDoSound is designed. It is probably possible in the future to just replace the SCI1.1 audio code (audio.cpp) with the new SCI32 code, since the major differences seem to be that (1) SCI1.1 only supported one digital audio playback channel (this is configurable already), (2) it had extra commands for CD audio playback and queued sample playback.
