From: Luiz Augusto von Dentz <luiz.von.dentz@xxxxxxxxx>
This adds avrcp_register_player function to register callbacks for
requests and responses, the fundamental difference is that the
callbacks are called after the original PDU is parsed and the parameter
are converted to host byte order making us able to unit test the
parsing itself.
