Original issue's description:
> Allow url::SchemeHostPort to hold non-file scheme without port
>
> WebSockets use url::Origin to pass origin info between renderer and
> browser. Currently, it cannot hold an origin with non-file scheme and
> no port. Chrome extensions have been using such origins, so we need
> to keep the channel to convey origin info work for such origins.
