Wrong port passed to URL authentication when listening on both :80 and :443

[bradisbell]

Suppose I have an Icecast server listening for HTTP on port 80, and HTTPS on port 443.

When I connect to a stream via HTTPS, the port parameter sent to a listener_add URL-based authentication handler indicates port 80 in the POST data. I'd expect it to indicate port 443.
