New way to provide DAC reference inputs (nw)
- Introduce MCFG_SOUND_REFERENCE_INPUT to provide fixed inputs through the resampler, eliminating the need for the "voltage regulator" device
- Replace memset use in sound.cpp with std::fill
This was my third implementation of this concept. The previous two involved attaching sound streams to the dummy device (which required giving it device_sound_interface and other modifications).
