Added SDL_AUDIO_ALLOW_SAMPLES_CHANGE flag enabling users of SDL_OpenAudioDevice to get
the sample size of the actual hardware buffer vs having a stream created to handle the
delta
add HAVE_ENDPOINTVOLUME_H, HAVE_MMDEVICEAPI_H and HAVE_AUDIOCLIENT_H
in SDL_config.h.in, SDL_config.h.cmake, SDL_config_windows.h, and in
SDL_config_winrt.h.

Patch a few warnings when using:
-Wmissing-prototypes -Wdocumentation -Wdocumentation-unknown-command
They are automatically enabled with -Wall

SDL_CreateTextureFromSurface makes an internal call to SDL_GetColorKey which can return an error and spams the error log with "Surface doesn't have a colorkey" even though the original function didn't return an error.

The SDL_syswm.h header includes the windows.h header after including begin_code.h which changes the structure packing alignment.
It seems this is not safe as suggested by the following warning :
warning C4121: 'JOBOBJECT_IO_RATE_CONTROL_INFORMATION_NATIVE_V2': alignment of a member was sensitive to packing

Forwarding from https://bugs.debian.org/892087 quoting verbatim:
The SDL2 header SDL_cpuinfo.h generates gcc warnings if the program using
it compiles with the -Wundef warning. (In particular, this means that QEMU
builds using it fail on at least sparc hosts, since QEMU dev builds
use both -Wundef and -Werror.).
/usr/include/SDL2/SDL_cpuinfo.h:63:5: warning: "HAVE_IMMINTRIN_H" is not defined, evaluates to 0 [-Wundef]
#if HAVE_IMMINTRIN_H && !defined(SDL_DISABLE_IMMINTRIN_H)
This tries to load vulkan.framework or libvulkan.1.dylib before MoltenVK.framework
or libMoltenVK.dylib. In the previous version, layers would not work for applications
run-time loading the default library.

This patch allows the user to disable the behaviour that blocks the compositor through a new hint: SDL_VIDEO_X11_NET_WM_BYPASS_COMPOSITOR. This allows tools or other windowed applications to behave properly under KWin.
This variable can be set to the following values:
"0" - The indicator bar is not hidden (default for windowed applications)
"1" - The indicator bar is hidden and is shown when the screen is touched (useful for movie playback applications)
"2" - The indicator bar is dim and the first swipe makes it visible and the second swipe performs the "home" action (default for fullscreen applications)

As discussed in 2012 the iOS onscreen keyboard hides when you hit RETURN (see https://discourse.libsdl.org/t/on-screen-keyboard-change/19216).
IMO this is a bad idea to not be able to influence this behavior and just recently this was fixed for Android by adding the hint SDL_HINT_ANDROID_RETURN_HIDES_IME in changeset 11768 6ce3bb5e38a5.

According to this GCC bug report, altivec.h requires building with the gnu extensions: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=78263.
As an application developer, I don't want SDL to force me to enable the gnu extensions.
This isn't complete, but is enough to run testsprite2. It's currently
Mac-only; with a little work to figure out how to properly glue in a Metal
layer to a UIView, this will likely work on iOS, too.
This is only wired up to the configure script right now, and disabled by
default. CMake and Xcode still need their bits filled in as appropriate.
XAudio2 doesn't have capture support, so WASAPI was to replace it; the holdout
was WinRT, which still needed it as its primary audio target until the WASAPI
code code be made to work.
The support matrix now looks like:
WinXP: directsound by default, winmm as a fallback for buggy drivers.
Vista+: WASAPI (directsound and winmm as fallbacks for debugging).
WinRT: WASAPI

Seems latest google angle library successfully built & tested under macOS'es.

We need to use GLES2 to implement true cross-platform code.
New functions get and set the YUV colorspace conversion mode:
SDL_SetYUVConversionMode()
SDL_GetYUVConversionMode()
SDL_GetYUVConversionModeForResolution()
SDL_ConvertPixels() converts between all supported RGB and YUV formats, with SSE acceleration for converting from planar YUV formats (YV12, NV12, etc) to common RGB/RGBA formats.
Added a new test program, testyuv, to verify correctness and speed of YUV conversion functionality.

I noticed that after updating SDL to 2.0.6 my application now exports SDL_main.
At GitHub SDL mirror (branch 2.0.5) SDL_main prototyped as
extern C_LINKAGE int SDL_main(int argc, char *argv[]);
but at branch 2.0.6 prototype is
extern C_LINKAGE DECLSPEC int SDL_main(int argc, char *argv[]);

EMX declares _beginthread() / _endthread() in stdlib.h, not process.h.
The attached patch updates the OS/2 case of SDL_thread.h for it. (It
also tidies the unreadable whitespace in win32 case.)
Note that apps submitted to the iOS App Store *must* use a modern iOS SDK (currently iOS 10 is probably the minimum), however the SDK used to build is separate from the minimum iOS version an app supports at runtime.

The patch below changes HAVE_COPYSIGN macro in SDL_config_windows.h to
HAVE__COPYSIGN, so that _copysign() can be used in SDL_stdlib.h which
is available in many more windows-targeting toolchains such as MinGW,
MSVC >= 6, etc, and not just MSVC >= 2013. SDL_stdlib.c already has a
specific check for HAVE__COPYSIGN, so I believe this is reasonable.
