Futz with the clang patch a bit and tidy some geoip.c stuff

[tor.git] / changes / bug2331

  o Minor bugfixes:
    - Add assertions to check for overflow in arguments to
      base32_encode and base32_decode; fix a signed-unsigned
      comparison there too.  These bugs are not actually reachable in
      Tor, but it's good to prevent future errors too.  Found by
      doorss.
