Now that this spin blocks at startup, I can use a standard atomic_flag.

Makes sure the timer really, really is on a different thread.

Thereby allows me substantially to reduce audio latency.

With some attempt at vsync prediction, seeks to smooth audio/video output.

There's plenty more work to do here, but hopefully it takes the issue immediately off the table.

Shunts audio into its own QThread.
...
For the record, this was the first means I found of attempting that which actually seemed to work. A plain QThread, with something `connect`ed to its `started` signal didn't seem to work (perhaps `connect` is smart at thread confinement?), `moveToThread` didn't work on the audio output after the fact, etc.

Simplifies AudioBuffer by consolidating logic into writes.
...
This is kind of fiddling in the margins though; I'm having a lot of difficulty determining the semantically-correct way to get Qt not to funnel all activity through a single thread.

Adds an additional buffer. To reduce latency. No, really.
...
Specifically: there's no way to guarantee no overbuffering due to the startup race, other than having QAudioOutput obtain data by pull rather than push. But if it's pulling then that implies an extra buffer. And since the sizes it may pull are not explicit, there's guesswork involved there.
So: no extra buffer => uncontrollable risk of over-buffering. Extra buffer => a controllable risk of over-buffering.

Actually, QIODevice is listed as reentrant. So no need to forward audio.
...
That said, latency is still absurd for some reason.

QIODevice isn't guaranteed thread safe, so use of it is now thread confined.

On the plus side, it does seem successfully to sniff out an appropriate audio format and to communicate mono/stereo onward.
