Comment:

 Please see my branch first-hop-no-private at
 https://github.com/teor2345/tor.git

 It modifies circuit_handle_first_hop to refuse any connections to a
 private address with a protocol error, unless ExtendAllowPrivateAddresses
 is set.

 This should catch this issue with relay extends, and hidden service / RSOS
 rendezvous from badly behaved clients.

 I can't test it on chutney, so I need help testing it on the live network.
 (Ugh.)
