- Allow sctp_ifa to be passed into inpcb_bind, addr_mgmt_ep_sa to bypass

- Moves all logging to use KTR. This gets rid of most
of the logging #ifdef's with a few exceptions reducing
the number of config options for SCTP.

Two major items here:
- All printf that was surrounded by #ifdef SCTP_DEBUG moves to
a macro that does all of this. This removes all printfs from
the code and makes the code more portable and easier to
read.
- Static Analysis (cisco) - found a few bugs, but mostly we
add checks for NULL pointers and such to make the tool
happy. We now pass the Cisco SA tools checks except for
where it does not understand tailq/lists. We still need
to look at the coverity tools output too (this is like
the cisco SA tool) and see if it wants us to fix any other
items. Hopefully this will be the last major churn in the
code other than bug fixes.

- Found bug in min split point bundling which caused
incorrect, non-bundlable fragmentation.
- Added min residual to better control split points for
both how big a msg must be as well as how much needs

- With our new algo in place, we need to implicitly
set "end of msg" on the sp-> structure otherwise we
end up with "hung" associations.
- Room reserved up front in IP header by pushing IP
header to back of mbuf.

will kill the assoc via the kill timer and send an
abort too.

- Do not strip off IP options anymore.
- Clean up sctp_calculate_rto().
- Get rid of unused sysctl.
- Fixed so we discard all M-Cast
- Fixed so port check done AFTER checksum
- Fixed bug in fragmentation code that prevented
us from fragmenting a small complete message when
we needed to.
- Window probes were not marked back to unsent and
flight adjusted when a sack came in with no
window change or accepting of the probe data.
We now fix this with having a mark on the net and
the chunk so we can clear it out when the sack arrives
forcing it to retran just like it was "new" this
improves the handling of window probes, which were
dropped by the receiver.
- Tighten AUTH protocol error checks during INIT/INIT-ACK exchange

- Auth code updated to current draft (this should be the
RFC version we think).
- use uint8_t instead of u_char in LOOPBACK address comparison
- Some u_int32_t converted to uint32_t (in crc code)
- A bug was found in the mib counts for ordered/unordered
count, this was fixed (was referencing a freed mbuf).
- SCTP_ASOCLOG_OF_TSNS added (code will probably disappear
after my testing completes. It allows us to keep a
small log on each assoc of the last 40 TSN's in/out and
stream assignment. It is NOT in options and so is only
good for private builds.
- Some CMT changes in prep for Jana fixing his problem
with reneging when CMT is enabled (Concurrent Multipath
Transfer = CMT).
- Some missing mib stats added.
- Correction to number of open assoc's count in mib
- Correction to os_bsd.h to get right sha2 macros
- Add of special AUTH_04 flags so you can compile the code
with the old format (in case the peer does not yet support
the latest auth code).
- Nonce sum was incorrectly being set in when ecn_nonce was
NOT on.
- LOR in listen with implicit bind found and fixed.
- Moved away from using mbuf's for socket options to using
just data pointers. The mbufs were used to harmonize
NetBSD code since both Net and Open used this method. We
have decided to move away from that and more conform to
FreeBSD style (which makes more sense).
- Very very nasty bug found in some of my "debug" code. The
cookie_how collision case tracking had an endless loop in
it if you got a second retransmission of a cookie collision
case. This would lock up a CPU .. ugly..
- auth function goes to using size_t instead of int which
conforms to socketapi better
- Found the nasty bug that happens after 9 days of testing.. you
get the data chunk, deliver it and due to the reference to a ch->
that every now and then has been deleted (depending on the postion
in the mbuf) you have an invalid ch->ch.flags.. and thus you don't
advance the stream sequence number.. so you block the stream
permanently. The fix is to make local variables of these guys
and set them up before you have any chance of trimming the
mbuf.
- style fix in sctp_util.h, not sure how this got bad maybe in
the last patch? (aka it may not be in the real source).
- Found interesting bug when using the extended snd/rcv info where
we would get an error on receiving with this. Thats because
it was NOT padded to the same size as the snd_rcv info. We
increase (add the pad) so the two structs are the same size
in sctp_uio.h
- In sctp_usrreq.c one of the most common things we did for
socket options was to cast the pointer and validate the size.
This as been macro-ized to help make the code more readable.
- in sctputil.c two things, the socketapi class found a missing
flag type (the next msg is a notification) and a missing
scope recovery was also fixed.

if a restart occur's and we release and relock (at
the point where we setup our alias vtag) we would
