not being aquired. This meant that when we cleanup
the outbound we may have one in transit to be
added with the old sequence number. This is bad
since then we loose a message :(
Also the report_outbound needed to have the right
lock when its called which it did not.. I added
the lock with of course a flag since we want to
have the lock before we call it in the restart
case.
This also fixed the FIX ME case where, in the cookie
collision case, we mark for retransmit any that
were bundled with the cookie that was dropped.
This also means changes to the output routine
so we can assure getting the COOKIE-ACK sent
BEFORE we retransmit the Data.

a colliding INIT. This if fine except when we have
data outstanding... we basically reset it to the
previous value it was.. so then we end up assigning
the same TSN to two different data chunks.
This patch:
1) Finds a missing lock for when we change the stream
numbers during COOKIE and INIT-ACK processing.. we
were NOT locking the send_buffer.. which COULD cause
problems (found by inspection looking for <2>)
2) Fixes a case during a colliding INIT where we incorrectly
reset the sending Sequence thus in some cases duplicately
assigning a TSN.
3) Additional enhancments to logging so we can see strm/tsn in
the receiver AND new tracking to watch what the sender
is doing with TSN and STRM seq's.

reset comes in we need to calculate the length and
therefore the number of listed streams (if any) based
on the TLV type. Otherwise if we get a retran we could
in theory panic by sending a notification to a user with
a incorrect list and thus no memory listing the streams.

copy's were incorrect and so was the locking.
-A bug was also found that would create a race and
panic when an abort arrived on a socket being read
from.
-Also fix the reader to get MSG_TRUNC when a partial
delivery is aborted.
-Also addresses a couple of coverity caught error path
memory leaks and a couple of other valid complaints

This also moves two 16 bit int's to become 32 bit
values so we do not have to use atomic_add_16.
Most of the changes are %p, casts and other various
nasty's that were in the orignal code base. With this
commit my machine will now do a build universe.. however
I as yet have not tested on a 64bit machine .. it may not work :-(
work is not just mine, but it is also the works of Peter Lei
and Michael Tuexen. They both are my two key other developers
working on the project.. and they need ata-boy's too:

I did do a make sysent which updated the
syscall's and sysproto.. I hope that is correct... without
it you don't build since we have new syscalls for SCTP :-0
So go out and look at the NOTES, add
option SCTP (make sure inet and inet6 are present too)
and play with SCTP.
I will see about comitting some test tools I have after I
figure out where I should place them. I also have a
lib (libsctp.a) that adds some of the missing socketapi
functions that I need to put into lib's.. I will talk
to George about this :-)
There may still be some 64 bit issues in here, none of
us have a 64 bit processor to test with yet.. Michael
may have a MAC but thats another beast too..
If you have a mac and want to use SCTP contact Michael
he maintains a web site with a loadable module with
this code :-)
