Quite a large commit, but mostly trivial. It adds all the (in dcSCTP) supported parameters, error causes and chunks as an object model, with serializers and deserializers. They are verified with packet captures where available, that have been captured with Wireshark against a reference implementation. This _could_ be split in parameter/ as one commit, error_cause/ in the following, and chunk/ as the third, but as each chunk/parameter is completely isolated from the other, reviewing it should be linear with the number of chunks/parameters and having them in more commits wouldn't change that, taken all those three commits into account.
