This removes the two separate callbacks for sending and receiving data to/from the device to a unified callback that's used for both input and output. The new callback takes a pointer to both an input and output buffer. When the device is opened in playback mode the input pointer will be set to null. Likewise the output pointer will be set to null for capture devices. Both input and output pointers will be non-null for full-duplex devices.
