* Routines for bitcoin dissection
* Copyright 2011, Christian Svensson <blue@cmd.nu>
* Bitcoin address: 15Y2EN5mLnsTt3CZBfgpnZR5SeLwu7WEHz
*
* See https://en.bitcoin.it/wiki/Protocol_specification
*
* Updated 2015, Laurenz Kamp <laurenz.kamp@gmx.de>
* Changes made:
* Updated dissectors:
* -> ping: ping packets now have a nonce.
* -> version: If version >= 70002, version messages have a relay flag.
* -> Messages with no payload: Added mempool and filterclear messages.
* Added dissectors:
* -> pong message
* -> notfound message
* -> reject message
* -> filterload
* -> filteradd
* -> merkleblock
* -> headers

* So: the loop should be executed only when 'tree' is defined so that the
* proto_ calls will throw an exception when the tvb is used up;
* This should only take a few-hundred loops at most.
