-SDL_RWops is now an opaque structure. The existing APIs to create a RWops (SDL_RWFromFile, etc) still function as expected, but to make a custom RWops with app-provided function pointers, call SDL_OpenRW and provide the function pointers through there.

 The RWops function pointers are now in a separate structure called SDL_RWopsInteface, which is provided to SDL_OpenRW. All the functions now take a `void *` userdata argument for their first parameter instead of an SDL_RWops, since that's now an opaque structure.
