Implements OPUS_{GET,SET}_LSB_DEPTH
...
This is used to avoid dynalloc doing silly things on periodic LSB
patterns and to reduce the bitrate on near-silence.

Fixes some overflows in the fixed-point pitch code
...
The overflows reported were:
- Syy in find_best_pitch() in pitch.c
- xy, xx and yy in remove_doubling() in pitch.c
The fixes are:
- Adaptive scaling in pitch_downsample() which also improves quality
- Adding a missing downshift in find_best_pitch()
- More conservative yshift when calling find_best_pitch()
