audio: change how filters are inserted on playback speed changes

Use a pseudo-filter when changing speed with resampling, instead of
somehow changing a samplerate somewhere. This uses the same underlying
mechanism, but is a bit more structured and cleaner. It also makes some
of the following changes easier.

Since we now always use filters to change audio speed, move most of the
work set_playback_speed() does to recreate_audio_filters().
