Implement the wildcard "*" protocol in {Client,Server}TransportPlugin lines
The spec says:
If instead of a transport method, the torrc lists "*" for a managed
proxy, Tor uses that proxy for all transport methods that the plugin
supports. So "ClientTransportPlugin * exec /usr/libexec/tor/foobar"
tells Tor that Tor should use the foobar plugin for every method that
the proxy supports. See the "Managed proxy interface" section below
for details on how Tor learns which methods a plugin supports.
