    Add some initial support for pluggable transports in TorNet
    
    We can now configure extorports and pt ports, and we can make a
    sort-of-plausible bridge line.
    
    We will need more work to get an actually correct bridge line, since
    
       1) we need to copy the 'cert' field out of the obfs state
          directory, and
       2) we will need to start the bridge before we can configure the
          client, which is not how we usually do things.
