syncduke: map the MusicVolume slider linearly in dB

The faithful percent->dB step left the MusicVolume slider mapping the game
0..255 to a 0..20 percent that SyncTERM then log-converted, so the slider
was lumpy near the bottom and the trim was the opaque number 20. Map the
slider LINEARLY IN DB instead -- how a real fader behaves -- between a
shared floor and a readable per-door trim: SD_MUSIC_TRIM_DB -14 (the old
SD_MUSIC_MAXV 20 in honest units) at the top, SD_MUSIC_FLOOR_DB -40 just
above the 0 = OFF cutoff.

Confirmed by ear. Same behaviour at the top of the slider; smoother, and a
touch quieter, through the middle.
