cdde6dd7bb Bumped deployment requirements for Apple platforms 
We require at least Xcode 12.2 and macOS SDK 11 to build. We support deploying to macOS 10.13, iOS 11.0, and tvOS 11.0.

This cleans up the code significantly

ac2edad809 audio: Simplify and unify audio stream format updating when devices change. 
This used to do different things for recording streams in different parts of
the codebase, not to mention two separate codepaths through
UpdateAudioStreamFormatsPhysical in any case. My hope is this should kill off
a few corner case bugs...for example, this one:

Fixes #8402.

80b9986418 audio: Fixed potential NULL dereference. 
This could happen if you call SDL_BindAudioStreams() when the subsystem isn't
initialized, and possibly in other corner cases.

Thanks to Qianxin CodeSafe Team, @QiAnXinCodeSafe, for discovering this issue!

Fixes #11643.

32cc92dceb pipewire: i/o callbacks should avoid higher-level iteration during device open. 
Sometimes these callbacks will fire while we're still waiting on state to
settle down in PIPEWIRE_OpenDevice, which means we're holding the device lock,
but then the i/o callback will fire from a background thread and also try to
grab the device lock, but can't, because PIPEWIRE_OpenDevice is holding it and
waiting for this i/o callback to finish...hence, a deadlock.

So now, if the device is still opening, output callbacks will write silence
and input callbacks will just flush the buffer, without calling the main
iterate function, and thus avoid obtaining the lock.

b6a6a4a7f8 audio: fix incorrect dynCall in Emscripten audio. 
This only seemed to cause problems with `-s ASYNCIFY` on the build command
line, but it was incorrect in general.

a90ad3b0e2 Removed SDL_bool in favor of plain bool 
We require stdbool.h in the build environment, so we might as well use the plain bool type.

If your environment doesn't have stdbool.h, this simple replacement will suffice:
typedef signed char bool;
