Dirty patch

I have an annoying issue on MacOS about XBoxOne Bluetooth rumble (Vendor: 0x045e, Product: 0x02fd).

When 360controller is installed, rumble is working correctly. However, Bluetooth rumble isn't working at all, with or without 360controller installed (although it is working with Chrome + https://html5gamepad.com).

I looked at the code, and it seems that XBox controllers are managed in MacOS in this file: SDL_hidapi_xbox360.c. The XBoxOne file is disabled for MacOS in SDL_hidjoystick_c.h.

The function HIDAPI_DriverXbox360_Rumble() is called correctly, and hid_write() returns no error.

I have tried a stupid test. I took the rumble packet from 360controller: https://github.com/360Controller/360Controller/blob/ec4e88eb2d2535e9b32561c702f42fb22b0a7f99/XBOBTFF/FFDriver.cpp#L620. With the patch I have attached, I manage to have rumble working on Bluetooth (with some stupid vibration level, but it proves it can if the packet is changed).

But it breaks the USB rumble with 360controller. A comment in the function makes an explicit reference to 360controller, I think that's why I have broken this specific usecase.

I don't know what is the correct way to fix this, but it seems that the current implementation has a missing case for Bluetooth support.


Note that I also tested master this morning, and I have another issue:
    if (!device->ffservice) {
        return SDL_Unsupported();
    }

test fails in DARWIN_JoystickRumble(). This test has been done quickly, I'm not totaly confident about its accuracy.
