I've limited the volume range to -100..+12 dB in my latest patch
now; this also avoids 4 chars in the status bar because the
lowest value is replaced by the mute symbol.

Another benefit of switching to dB for volume is that it makes
it easy to add clipping prevention at the app level, without
needing knowledge about the specific DAC. We just need to make
sure that

current_volume + MAX(bass_boost, treble_boost) <= max_volume

by reducing either current_volume (not good; old system for
player & iriver) or bass_boost and treble_boost (better).

Making this happen at the app layer also makes it easier to
indicate what's happening.
