ABORT cause, since the user can also provide this kind of

information.

ABORT chunk when using a send() call with SCTP_ABORT|SCT_SENDALL

* Decouple the path supervision using a separate HB timer per path.
* Add support for potentially failed state.
* Bring back RTO.min to 1 second.
* Accept packets on IP-addresses already announced via an ASCONF
* While there: do some cleanups.

e6194c2ed4 Improve compilation of SCTP code without INET support. 
Some bugs where fixed while doing this:
* ASCONF-ACK messages might use wrong port number when using
  IPv6.
* Checking for additional addresses takes the correct address
  into account and also does not do more comparisons than
  necessary.

This patch is based on one received from bz@ who was
sponsored by The FreeBSD Foundation and iXsystems.

f79aab1866 Tunes and fixes the new DC-CC to seem to hit the 
right mix.  Still may need some tweaks but it
appears to almost not give away too much to an
RFC2581 flow, but can really minimize the amount of
buffers used in the net.
