dep/cubeb: Sync to 19fcbef

And apply PR #740 (Re-enable and polish IAudioClient3 to achieve lower
latencies).

`*latency_frames = min_period;` in wasapi_get_min_latency was changed to
`*latency_frames = hns_to_frames(params.rate, min_period_rt);`, as
otherwise it reports in mixer frames, not stream frames.
