Merge #2939: [Net]: Add compatibility for miniupnpc 2.2.8

4fffec0 upnp: add compatibility for miniupnpc 2.2.8 (Cory Fields)

Pull request description:

  See: miniupnp/miniupnp@c0a50ce

  The return value of 2 now indicates:
  "A valid connected IGD has been found but its IP address is reserved (non routable)"

  We continue to ignore any return value other than 1.
