 When replying, checking the address family of the local address only works
 under the assumption that the local socket type is the same as the
 destination socket. This was true, until we began supporting AF_UNIX
 socksports. The result is now that when tor replies to an application over
 a unix socket, it specifies that it connected to an IPv6 address, when
 it's possible it connected to an IPv4 address. It seems like a good idea
 that we base this on the address family of the destination address.
