* Added a destructor to clean up TLS memory at thread shutdown
* Refactored the TLS code to have platform independent code and a small platform dependent core with a fallback to generic code if platform dependent functions fail.
* Fixed recursion issues with SDL_GetErrBuf()
This ensures that we only no-op redundant calls if they're made on the
same thread as the last MakeCurrent with those arguments. This should
maek SDL behave better with multithreaded environments.
This code was written almost 2 years ago, and the flag hasn't been
changed since. Cleaning up the code by removing the conditional blocks,
so that they behave the same way they have for the past two years.
FULLSCREEN_TOGGLEABLE used to cause us to use
-[NSOpenGLContext setFullScreen] and a pixel format with
NSOpenGLPFAFullScreen.
Unexplicable computer sciences phenomenon: Instead of returning an empty set,
*.c in an folder with no .c files produces the "*.c" string to be added as
a source. I'm sorry future generations, we are doing the best we can :)
The implementation was slower than the C runtime on Mac OS X, Linux, and
Windows...quite a bit slower when using the C fallback instead of the inline
asm, too.
Fixes Bugzilla #1755.

While BMP format supports alpha channel, it is enabled only when the header is at least 56 bytes long (BITMAPV3INFOHEADER and later). For very common 40-byte-long header (BITMAPINFOHEADER) 32bpp format should be interpreted as BGRX format, but currently SDL interprets them as BGRA format and causes a significant compatibility problem as many 32bpp files use a padding byte of 0 ("transparent" in BGRA interpretation).

I fixed this by checking to see if the alpha channel is all 0, and if so, setting it opaque.

1/ Load an Image XPM with IMG_ReadXPMFromArray()
2/ Try to set a ColorKey on it.
I notice that :
- the SDL_Surface that is created from XPM has a palette !
- the colorkey is a RBG.
it crashes (SIGSEGV) inside the SDL_SetColorKey function:
"surface->format->palette->colors[surface->map->info.colorkey].a"

I find that the calling point in SDL_uikitappdelegate.m is dangerous as the -(void) postFinishLaunch method can be overridden when subclassing.
Could this be moved in inside the init or in the didFinishLaunchingWithOptions method which are always called even when subclassed?
Having the SDL functions inline is causing build issues, and in the case of malloc(), etc. causing malloc/free mismatches, if the application build environment differs from the SDL build environment.
In the interest of safety and consistency, the functions will always be in the SDL library and will only be redirected to the C library there, if they are available.
See the following threads on the SDL mailing list for the gruesome details:
* SDL_stdinc.h inlines problematic when application not compiled in exact same feature environment
* Error compiling program against SDL2 with -std=c++11 g++ flag
