The BitTorrent dissector fails on certain traces with not handled message IDs.
ID=9: port
see http://wiki.theory.org/BitTorrentSpecification
ID=20: extended message
see http://www.bittorrent.org/beps/bep_0010.html
The attached patch implements handling the two message IDs. It does not handle
the content of the extended message.
I have no traces to show the messages, but I will try to generate some, if
required.
Without the patch, wireshark fails to analyse subsequent bittorrent messages.
