It's been hardcoded out forever now, but I've now forcibly removed it with
the preprocessor so static analysis doesn't complain about it for now.
Eventually I want to rewrite or remove this code.
- Use the SDL_AUDIO_MASK_DATATYPE bit when selecting an implementation
where it matters. Previously two existing AUDIO_F32 cases had been
written, but were unreachable.
- Add AUDIO_F32 case for SDL_ConvertSurround_4.
- Fix incorrect pointer arithmetic causing the 2 to 6 channel
conversion for 4 byte audio formats to read and write beyond the end
of the buffer.
SDL 2.x recently accepted patches to enable OpenGL ES 2 support via Google's ANGLE library. The thought is to try to eventually merge SDL/WinRT's OpenGL code with SDL-official's.
Haiku uses most of the standard pthread API, with a few #ifdefs where we
still need to fallback onto the old BeOS APIs.
BeOS, however, does not support pthreads (or maybe doesn't support it well),
so I'm unplugging support for the platform with this changeset. Be Inc went
out of business in 2001.

The audio_enumerateAndNameAudioDevicesNegativeTests test in testautomation_audio.c reports a failure for SDL_GetAudioDeviceName when called on a driver that has only the default device. SDL_GetNumAudioDevices reports 1, but SDL_GetAudioDeviceName does not check if the index passed by the caller is in that range in this case. For positive numbers anyway.
This can be reproduced with the dummy driver on Windows and Linux.

The problem in question is caused by changeset 7771 (http://hg.libsdl.org/SDL/rev/4434498bf4b9 / https://bugzilla.libsdl.org/show_bug.cgi?id=2121)
The redefinition of __inline__ (introduced by the addition of begin_code.h:128's "|| __STRICT_ANSI__") results in mingw's gcc throwing multiple
warning: always_inline function might not be inlinable [-Wattributes]
as well as a whole bunch of redefinitions of mingw internals which break linking of projects including the SDL2 headers.
XAudio2 2.8's header file, xaudio2.h, doesn't compile in plain C code for WinRT
apps, not automatically at least. Initially, this file was adapted to compile
as C++, however these changes are now deprecated in favor of some preprocessor
based hacks that should get xaudio2.h to compile (while making sure XAudio2
still works).
Newer libpulses do sane defaults if you pass a NULL there. In lieu of a
proper way to specify this in SDL at the moment, this will do.
Fixes Bugzilla #1119.
This #errors if you're using an SDK or deployment target that is less
than 10.6 and 10.5, respectively, and cleans up uses of
MAC_OS_X_VERSION_MIN_REQUIRED and MAC_OS_X_VERSION_MAX_ALLOWED according
to those requirements.
It now tries to make sure the hardware can support a given format, and if it
can't, it carries on to the next best format instead of failing completely.
Otherwise, you can pause audio and still have the callback running, or run
one more time. This makes sure the callback is definitely stopped by the
time you return from SDL_PauseAudio().
This is what SDL 1.2 did; we'll do this properly (add a method for the target
driver to pause) when I rewrite all this code after the official 2.0 release.
Fixes Bugzilla #1857.

Pulse has supported (since version 0.8, at least) 32 bit audio formats that are now becoming available in SDL2. This patch adds those format conversions to the switch clause in the pulseaudio backend.
