Unlike SDL_Rect (typedef struct SDL_Rect {} SDL_Rect), SDL_Point (typedef struct {} SDL_Point) structure is unnamed. This feels inconsistent and makes it impossible to use forward declaration for SDL_Point, having to include whole SDL_rect.h instead.
The SDL OpenGL context code is now properly thread aware. There are two new functions which return the current OpenGL window and context for the current thread.
There are still places in the cocoa driver where the OpenGL context needs to be updated when the view changes. These will need a different solution and still use the last globally set context to avoid changing behavior.
* 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()
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.
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
This broke Steam's Big Picture game controller support.
I also added some more documentation so people know why main() is overridden on various platforms.

SDL_Keysym contains a deprecated field for unicode which may be removed for SDL 2.0 release.
As far as I can tell the field is not set on all "major" platforms and therefore will not be useful for most users. Its existence in a public header therefore becomes (in my opinion) only confusing.
This will help reduce issues like that reported in bug 1819:

This changes makes it so that you only receive joystick (and implicitly
gamecontroller) input events when your application has keyboard focus.
If you'd like to still receive events when your application is in the
background, set the SDL_JOYSTICK_ALLOW_BACKGROUND_EVENTS hint to "1".
