Allows a protocol to override blacklisted ports.

This method will be called when there is an attempt to connect to a port that is blacklisted. For example, for most protocols, port 25 (Simple Mail Transfer) is banned. When a URI containing this "known-to-do-bad-things" port number is encountered, this function will be called to ask if the protocol handler wants to override the ban.

Constructs a new channel from the given URI for this protocol handler and sets the loadInfo for the constructed channel.
