Nick Mathewson b7c172c9ec Disable extending to private/internal addresses by default
This is important, since otherwise an attacker can use timing info
to probe the internal network.

Also, add an option (ExtendAllowPrivateAddresses) so that
TestingTorNetwork won't break.

Fix for bug 6710; bugfix on all released versions of Tor.

o Major bugfixes (security):
- Reject any attempt to extend to an internal address. Without
this fix, a router could be used to probe addresses on an
internal network to see whether they were accepting
connections. Fix for bug 6710; bugfix on all released versions
of Tor.
