daemon.conf isn't really the place to configure the stream
prioritization policy. It won't scale to more complex rules, and I don't
want to split things so that some prioritization schemes are configured
in daemon.conf and some are configured in routing modules.

I haven't looked at the code of this new module, but I think the general
idea is fine as long as we don't have more comprehensive configuration
facilities for routing.
