553b328664 Fixed bug 3668 - Overflow of SDL_AudioCVT.filters with some downmixes 
Simon Hug

There's a chance that an audio conversion from many channels to a few can use more than 9 audio filters. SDL_AudioCVT has 10 SDL_AudioFilter pointers of which one has to be the terminating NULL pointer. The SDL code has no checks for this limit. If it overflows there can be stack or heap corruption or a call to 0xa.

Attached patch adds a function that checks for this limit and throws an error if it is reached. Also adds some documentation.

Test parameters that trigger this issue:
AUDIO_U16MSB with 224 channels at 46359 Hz
                 V
AUDIO_S16MSB with 6 channels at 27463 Hz

The fuzzer program I uploaded in bug 3667 has more of them.

3c955d0540 syswm: prevent buffer overflow if SDL and app have different config headers. 
This only affects Wayland and DirectFB, as a Unix system generally has X11
support. Other platforms also have different sizes for the C union in
question, but are likely the only target for that platform, etc.

Apps that might run on Wayland or DirectFB will need to be compiled against
new headers from an official 2.0.6 release, or be prepared to force the x11
target, or not use SDL_GetWindowWMInfo().

Fixes Bugzilla #3428.

43d62b7459 Make compile-time assert error messages more clear. 
Now the compiler might say this:

'SDL_compile_time_assert_mytest' declared as an array with a negative size

instead of

'SDL_dummy_mytest' declared as an array with a negative size

6d661cab7b windows: Change the default on SDL_HINT_WINDOWS_DISABLE_THREAD_NAMING. 
It's easier for Visual Studio users that want this information to turn it on
or live without it, than it is to explain why every debugger that isn't Visual
Studio crashes out here. Eventually SetThreadDescription() will be the thing
everyone uses anyhow.

Fixes Bugzilla #3645.
