For some reason mp_fifo specifically handled double clicks, and other than that was a pointless wrapper around input.c functionality. Move the double click handling into input.c, and get rid of mp_fifo. Add some compatibility wrappers, because so much VO code uses these functions. Where struct mp_fifo is still used it's just a casted struct input_ctx.
