This commit adds support for controling the use of encryption and
setting the broadcast code. This is done as part of the endpoint.config
command. For source endpoints the encryption flag and broadcast code can
be set, while the sink supports only broadcast code setting. If no custom
broadcast code is provided, the default one will be used.
