Fix hwengine crash when using >1 controllers Reason: Data type mismatch for SDL_JoystickName, we wed in an index, but it expected a controller handle. Solution: Switch to SDL_JoystickNameForIndex.

void fpcrtl_halt(int num) {
    __coverity_panic__();
}

int fpcrtl_abs(int num) {
    return num >= 0 ? num : -num;
}
