b8c802632b 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:

https://developer.android.com/ndk/guides/audio/opensl/opensl-for-android

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

Fixes #13779.

afc1d9122b pipewire: Report correct device default formats instead of hardcoding Float32. 
The comment in the source wasn't true; PipeWire doesn't _have_ to work in
float format. It presumably does if it has to mix, but if a game is the only
thing making noise on the system--a common scenario--then it might be able to
pass, say, Sint16 data straight through to the hardware without conversion.

Fixes #12129.

24693ac285 Changed PULSEAUDIO_FlushRecording() to only flush audio present when called. 
When the flushing is not able to keep up with the audio stream coming in,
it will end up flushing forever and block API clients from getting any audio.

20574c016a coreaudio: Workaround for crash when disconnecting a bluetooth audio device. 
Our understanding of what's going on here might be incorrect, but it seems
like we're getting this callback at a point where we shouldn't be able to,
with a device we've already closed.

If we're on the wrong track, this code should still be harmless; it just
verifies a device is still in the open list before dereferencing it.

Reference Issue #10432.

17b9ed7d82 audio: Favor OpenSL ES over AAudio. 
There are low-latency fixes in SDL3 that really need to be backported to SDL2
before AAudio will be nicer across a range of devices, so OpenSL ES is safer
in SDL2 at the moment. At least, we suspect as such.

Fixes #11457.

d2b9ecd281 Revert "aaudio: Set low-latency audio mode." 
This reverts commit 1e016fd5ea.

In order to use low latency mode, you need to set low latency callbacks. This has always been recommended and is apparently required on Android 15. SDL3 has these implemented correctly but SDL2 does not, so we should revert this for now.

58f2586b44 pulseaudio: Hotplug thread fixes. 
This used a tiny stack, which apparently upsets Blender for various
technical reasons. Instead, just use the default stack size, which should
give it plenty of space to work.

If the thread failed to create, we would then wait on a semaphore that would
never trigger, so don't do that anymore!

Fixes #10806.

https://stackoverflow.com/questions/42125/warning-error-function-declaration-isnt-a-prototype
In C int foo() and int foo(void) are different functions. int foo() accepts an arbitrary number of arguments, while int foo(void) accepts 0 arguments. In C++ they mean the same thing.

510f413bb8 coreaudio: simplify memory leak fix. 
I _did_ appreciate the explanation, but it doesn't have to live in the
source code; also we can just release `devuid` and then check for error with
the usual macro, since SDL is done with it either way at this point.

1e2f311811 audio: backport SDL3's audio datatype converters. 
These are faster and more precise.

This did not change the Uint16 versions (as SDL3 dropped them, and honestly
no one should be using them in SDL2), nor the NEON converters (as this was
not changed in SDL3, so far).
