  o Code refactoring:
    - Tweak tor-fw-helper to accept an arbitrary amount of arbitrary
      TCP ports to forward. In the past it only accepted two ports:
      the ORPort and the DirPort.
General tweaks and fixes for Nick's comments. * Add changes/ files. * Edit the tor-fw-helper manpage. * Fix check-spaces. * Add prototype for get_list_of_ports_to_forward(). * Fix tor_parse_long() TCP port range. * Improve doc. of tor_check_port_forwarding(). * Check for overflows in tor_check_port_forwarding(). * Demote successful port forwarding to LOG_INFO.
