Modified Files:
        src/sys/dev/audio: audio.c audiobell.c audiodef.h audiovar.h

Log Message:
Improve audiobell (and interfaces with audio).
- Generate pseudo sine wave if possible.  It may improve timbre.
  If it cannot represent a sine wave, it falls back to a triangular
  wave or a rectangular wave.
- Volume adjustment.
- Calculate playback frequency based on mixer frequency.
  Now audiobellopen() initializes playback parameters other than
  sample_rate, and new audiobellsetrate() sets sample_rate.
