This adds support for all XInput devices, exposed through the SDL joystick API. The button and axis reporting for XInput devices has been changed to match DirectInput and other platforms. The game controller xinput mapping has been updated so this change is seamless. There is a new hint, SDL_HINT_XINPUT_USE_OLD_JOYSTICK_MAPPING, for any applications that have hardcoded the old xinput button and axis set. This hint will be removed in SDL 2.1.
