0. Avoid calling `soundio_panic` in PulseAudio.

0. PulseAudio: when prebuf gets set to 0 need to pass `PA_STREAM_START_CORKED`.

0. clear buffer maybe could take an argument to say how many frames to not clear

`pa_stream_flush`, then uncork the stream.

0. API: devices should reference to their "other" device when the same
