To be able to label incoming tor connections as different from normal localhost connections in e.g. `getpeerinfo` and the peers list in the GUI it'd be useful to have them connect on an alternative local-only port. Or even better, a UNIX socket.

For manually set-up hidden services this would have to be configured manually and could add a `hsport` option or such. The external port would still appear as `XXXXXXXXX.onion:8333`, however internally it would redirect to a that port.

In the case of `torcontrol` this would be easy to set up automatically. It could add a new (localhost) binding port automatically and this code would have to be changed:

    if (node.connman) {
        node.connman->StopThreads();
        LOCK2(::cs_main, ::g_cs_orphans);
        node.connman->StopNodes();
    }
    StopTorControl();
    
    
    if (node.scheduler) node.scheduler->stop();
    if (g_load_block.joinable()) g_load_block.join();
    threadGroup.interrupt_all();
    threadGroup.join_all();
    
    
    node.peerman.reset();
    node.connman.reset();
    node.banman.reset();
    if (node.mempool && node.mempool->IsLoaded() && node.args->GetArg("-persistmempool", DEFAULT_PERSIST_MEMPOOL)) {
        DumpMempool(*node.mempool);
