Comment (by callumw):

 Would this suffice for a new tor_getsockname function?

 MOCK_IMPL(int,
 tor_getsockname,(tor_socket_t sock, struct sockaddr *sock_address,
                  tor_addr_t *tor_address, socklen_t *address_len))
 {
    if (getsockname(sock, address, address_len) < 0) { return -1 }

    return tor_addr_from_sockaddr(&tor_address, (struct
 sockaddr*)&sock_address, NULL);
 }

 I have done it this way so that each call to tor_getsockname can be dealt
 with individually as they are now with getsockname.
