351d6d4784 audio: Port WASAPI to WinRT, remove XAudio2 backend.
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

16b8c4ea43 Fixed bug 3811 - change HAVE_COPYSIGN to HAVE__COPYSIGN in SDL_config_windows.h
Ozkan Sezer

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.

be1caece4a Correction: copysign has been supported by windows several toolchains
for a very long time, including MSVC6, MinGW, LCC-Win32, (no released
watcom versions though, but that's of no concern.)

f465f24d73 Fixed bug 3760 - RWops doesn't check for integer overflow when stdio_fseek only supports 32 bits
Simon Hug

When RWops seeks with fseek or fseeko it uses the types long or off_t which can be 32 bits on some platforms. stdio_seek does not check if the 64-bit integer for the offset fits into a 32-bit integer. Offsets equal or larger than 2 GiB will have implementation-defined behavior and failure states would be very confusing to debug.

The attached patch adds range checking by using the macros from limits.h for long type and some bit shifting for off_t because POSIX couldn't be bothered to specify min and max macros.

It also defines HAVE_FSEEKI64 in SDL_config_windows.h so that the Windows function gets picked up automatically with the default config.

And there's an additional error message for when ftell fails.

d51dc7378b Fixed bug 3797 - configure check for float.h
Ozkan Sezer

Cmake checks for float.h, but configure does not:  the attached patch
adds float.h to checked headers in configury, and it adds the missing
HAVE_FLOAT_H macro to SDL_config.h.cmake and SDL_config.h.in.

In SDL_config_macosx.h and SDL_config_windows.h, defined HAVE_FLOAT_H
as 1, where I know that it's true.

30d554e3d6 Fixed building SDL applications with Visual Studio and the clang toolset
Also fixed building 64-bit SDL with clang. 32-bit doesn't build because of the inline assembly for C runtime support.

6046fd4cb0 wasapi: Initial WASAPI support, for Windows Vista and later.
This should remain binary compatible with Windows XP, as we dynamically
load anything we need and fall back to DirectSound/WinMM/XAudio2 if not
available.

0e45984fa0 Fixed crash if initialization of EGL failed but was tried again later.
The internal function SDL_EGL_LoadLibrary() did not delete and remove a mostly
uninitialized data structure if loading the library first failed. A later try to
use EGL then skipped initialization and assumed it was previously successful
because the data structure now already existed. This led to at least one crash
in the internal function SDL_EGL_ChooseConfig() because a NULL pointer was
dereferenced to make a call to eglBindAPI().
