This patch contains changes needed for retiming sound strips. `BKE_sound_set_scene_sound_pitch()` is replaced by `BKE_sound_set_scene_sound_pitch_constant_range()` which uses new Audaspace interface to set pitch in bulk. This is done in `SEQ_retiming_sound_animation_data_set()` where retimed sections are created for each strip. When strip is inside of meta strip(s), the retimed sections of meta and actual strip are split where they intersect and pitch is multiplied where they overlap. Each section will have pitch value that is provided to audaspace. Waveform overlay now represents retimed audio accurately.
