[Proposal] Support port mapping in tor/listen.go

[parazyd]

This is a feature request.

Would it be possible to support port maps like stem does in tor/listen.go?

For example, in stem we can do:

service = controller.create_ephemeral_hidden_service({80: 5000, 90:5001}, await_publication = True)

This would yield two listeners, on ports 5000 and 5001, and it would map them to 80 and 90.

Yeah, today I only support one LocalPort/LocalListener in the simplified listen API in the tor package (but we do support multiple remote ports). There's no specific reason not to accept more ports/listeners (e.g. AdditionalLocalPorts/AdditionaLocalListeners to retain backwards compatibility). I haven't been able to work on this project in a while, so who knows if/when it'll be impl'd. In the meantime, code can use the lower-level pieces to communicate directly w/ the control port using the control package the way the Listen call does.

if I revisit this, I think I may accept a port-mappings structure that will be mutually exclusive with the existing local/remote port pieces. This will give the most flexibility.
