Code from the hack-session known as the IETF (and a

bit of debugging afterwards):
- Fix protection code for notification generation.
- Decouple associd from vtag
- Allow vtags to have less strigent requirements in non-uniqueness.
   o don't pre-hash them when you issue one in a cookie.
   o Allow duplicates and use addresses and ports to
     discriminate amongst the duplicates during lookup.
- Add support for the NAT draft draft-ietf-behave-sctpnat-00, this
  is still experimental and needs more extensive testing with the
  Jason Butt ipfw changes.
- Support for the SENDER_DRY event to get DTLS in OpenSSL working
  with a set of patches from Michael Tuexen (hopefully heading to OpenSSL soon).
- Update the support of SCTP-AUTH by Peter Lei.
- Use macros for refcounting.
- Fix MTU for UDP encapsulation.
- Fix reporting back of unsent data.
- Update assoc send counter handling to be consistent with endpoint sent counter.
- Fix a bug in PR-SCTP.
- Fix so we only send another FWD-TSN when a SACK arrives IF and only
  if the adv-peer-ack point progressed. However we still make sure
  a timer is running if we do have an adv_peer_ack point.
- Fix PR-SCTP bug where chunks were retransmitted if they are sent
  unreliable but not abandoned yet.

With the help of:	Michael Teuxen and Peter Lei :-)
