Fixed bug 1882 - SDL_GetKeyboardState should return const.

Browse source 
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.
