This tries to make our code a bit more compliant with our code formatting
conventions. For future use, this is the command I used:
git ls-files "*.cpp" "*.h" | xargs sed -i -e 's/[ \t]*$//'
Many engines follow the advice in audio/midiparser.h and create a
"pseudo-MidiDriver" subclass. But MidiParser really only needs a tiny
subset of the MidiDriver capabilities, namely those found in
MidiDriver_BASE. So we try to subclass from that whenever possible; this
allows us to remove many stub methods, and enables further future
simplifications.
- FM-Towns euphony driver completely rewritten based on KYRA FM-Towns and LOOM towns disasm.
- Split all the emu and driver code from sound_towns.cpp into different files to make things a bit less confusing.
- Move the driver code to common space since the exact same euphony driver is used by LOOM which means we could get rid of the outdated and incomplete ym2612 driver/emu implementation (which doesn't even do things like instrument loading, pan position, etc). I haven't tried to add this to the Scumm engine yet, since I am not familiar with it and my priority was to get the driver finished first. But from the look of disasm it shouldn't be difficult to do.
- Introduce a generic FM-Towns audio interface based on FM-Towns system file disasm which was necessary for the euphony driver rewrite. Every FM-Towns game I have seen so far seems to access the audio hardware via these system functions. This interface implementation will also allow reasonably simple creation of new FM-Towns audio drivers (e.g. this could be used for Kings Quest 5 FM-Towns or others).
- Move the PC98 driver to common space, too, since I have a strong feeling that this driver is also used in the PC98 version of Future Wars
- This also improves KYRA FM-Towns music quality, sound effects accuracy and music fading.

- Made the future versions of sound.h GPL only
- sound_adlib.h is dual licensed under GPL and LGPL (so AdPlug can still benefit from future changes)
