Merge branch 'wss-sb16' into sb16_merge
...
Bring in SB16/WSS support (bufferless SB DSP, AD1848, SB mixer, IRQ/DMA configuration) and 0.12 fixed-point volume scaling from wss-sb16, and combine with stereo OPL3 pipeline and lock-free SPSC audio FIFO from sb16_merge.
Conflict resolutions:
- volctrl.h: use 0.12 scale from wss-sb16 (no int64_t)
- sbplay.cpp: keep stereo opl_resample_tick() with clamp16 before resampler buffers; lock-free SPSC FIFO reads with stereo volume; add sbdsp_process() from wss-sb16
- pgusinit.c: use wss-sb16's full BLASTER parser (A/I/D/H/T fields)
