The Nintendo Wii Remote requires binary bluetooth addresses as PINs.
This is not possible via dbus agent API. So this adds a plugin that
registers a pin-callback and forces the right pin for every
authentication request of wiimotes.

+ * Nintendo Wii Remote devices require the bdaddr of the host as pin input for
+ * authentication. This plugin registers a pin-callback and forces this pin
+ * to be used for authentication.
+ *
+ * There are two ways to place the wiimote into discoverable mode.
+ * - Pressing the red-sync button on the back of the wiimote. This module
+ * supports pairing via this method. Auto-reconnect should be possible after
+ * the device was paired once.
+ * - Pressing the 1+2 buttons on the front of the wiimote. This module does
+ * not support this method since this method never enables auto-reconnect.
+ * Hence, pairing is not needed. Use it without pairing if you want.
+ * After connecting the wiimote you should immediately connect to the input
+ * service of the wiimote. If you don't, the wiimote will close the connection.
+ * The wiimote waits about 5 seconds until it turns off again.
+ * Auto-reconnect is only enabled when pairing with the wiimote via the red
+ * sync-button and then connecting to the input service. If you do not connect
+ * to the input service, then auto-reconnect is not enabled.
+ * If enabled, the wiimote connects to the host automatically when any button
+ * is pressed.
