2f4919c6ff Use 20 ms as the default audio buffer size on Android 
It turns out that Android will not pick a low latency buffer size by default.

054bea938a dummyaudio: Remove bitrotted support for __EMSCRIPTEN_PTHREADS__ code path. 
In SDL_audio.c:OpenPhysicalAudioDevice, an attempt is made to SDL_CreateThread
if ProvidesOwnCallbackThread is false, but SDL_CreateThreadWithPropertiesRuntime
is not implemented for Emscripten, so this always fails. I'm not sure if/when
this ever worked, but it simply cannot work in its current state.

7d66d3271b emscriptenaudio: Don't force reset SDL3.audio_recording/audio_playback.

b681862f14 emscripten: Don't pass an argument to MAIN_THREAD_EM_ASM_INT we don't use. 
This upsets things, because you end up calling a javascript function with
more arguments than it expects, and if asserts are enabled, Emscripten notices
this and aborts the program when you hit this code.

Reference Issue #14670.

0d2f081d41 pulseaudio: Match channel map to SDL's chosen order 
pa_channel_map_init_auto() with PA_CHANNEL_MAP_WAVEEX does the wrong
thing as it just takes the lest significant bits of
WAVEFORMATEXTENSIBLE's dwChannelMask in order. This doesn't match SDL's
chosen channel ordering.

The implementation here mirrors what we do for PipeWire.

65e462a6f2 audio: Handle device disconnects on the main thread. 
This avoids situations like:

- PulseAudio holds its own lock in the hotplug thread.
- The hotplug thread notices a device went away.
- The hotplug thread calls SDL_AudioDeviceDisconnected().
- SDL_AudioDeviceDisconnected() tries to grab the device lock.
- The device thread is holding the device lock...
- ...but is currently waiting on PulseAudio's lock to release.

In short: deadlock. It's better to queue this work to run on the main thread,
where we can guarantee a start with _none_ of the audio subsystem locks held.

0b2a003a35 openslES: OpenSL ES on Android only supports two formats, limit to that. 
(Three with the floating point extension, which we use.)

This is according to:

Previously, this would accept a request for Sint8 or Sint32 and disaster
would ensue.
