Dualshock4 on bluetooth need 78 bytes for the rumble data while SDL_HIDAPI_RumbleRequest can only hold 64 bytes.
'volatile' is not meant for thread synchronization.
The list of rumble request could grow infinitely if user call SDL_JoystickRumble too much. The documentation says "Each call to this function cancels any previous rumble effect", so overwriting pending request seem like a good idea.
