Fixed testnative on Mac OS X, which no longer ships X11 by default.
Fixed bug 1882 - SDL_GetKeyboardState should return const.

Yuri K. Schlesner

The array returned by SDL_GetKeyboardState is also used internally by SDL to keep track of pressed/released keys and must not be modified, lest weird behaviour occurs. Because of this I believe it's return type should be changed to return a const pointer, which will provide a code indication of that fact.
Fixed bug 1881 - SDL will not compile with "SDL_THREADS" disabled.

I am attempting to compile SDL on WindowsXP 32-bit, using MinGW.  The problem I am having is when I attempt to compile, when it gets to "SDL_systhread.c" it errors:

C:\Repos\Mezzanine\Mezzanine\libincludes\common\sdlsrc\SDL\src\thread\generic\SDL_systhread.c|29|error: conflicting types for 'SDL_SYS_CreateThread'
C:\Repos\Mezzanine\Mezzanine\libincludes\common\sdlsrc\SDL\src\thread\generic\..\SDL_systhread.h|35|note: previous declaration of 'SDL_SYS_CreateThread' was here

I do have SDL_THREADS disabled in my cmake configuration as I do not want or need SDL making threads for me, I have another thread provider.  It seems the generic "dummy" implementation does not account for the two extra parameters needed for the "SDL_SYS_CreateThread" method when "SDL_PASSED_BEGINTHREAD_ENDTHREAD" is defined.
Gyrations to get the code to compile with the latest version of mingw-w64 as well as Visual Studio.
I think in this case mingw-w64 is incorrect in defining the GUID instead of declaring it like Visual Studio and the older mingw32 compilers.
