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()
