- For sctp_input/sctp6_input add announcment when a packet arrives (debug)
- re-factor the packet drop in sctp_output a bit more, we don't need the
trim after all, but the size calc is now corrected.
- When a assoc is in the COOKIE-ECHO/COOKIE-WAIT state and the user
closes, it should not matter if data is queued, the assoc should be
purged.
- In error leg a missing free_chunk when iph comes in NULL (should not
happen but just in case).
