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.

behavior of sockstat(1) will still be to show "udp", "tcp" and
"divert" protocols, but we can now provide a (comma-separated)
list of protocols, as in:
% sockstat -P tcp
to list only TCP sockets, or we can filter more than one protocol
by separating the protocol names with a comma:
% sockstat -P tcp,udp
Protocol names are parsed with getprotobyname(3), so any protocol
whose name is listed in `/etc/protocols' should work fine.

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.

wait (time waited to acquire) and hold times for *all* kernel locks. If
the architecture has a system synchronized TSC, the profiling code will
use that - thereby minimizing profiling overhead. Large chunks of profiling
code have been moved out of line, the overhead measured on the T1 for when
it is compiled in but not enabled is < 1%.

The old message implied to me that ACPI can't be compiled in on platforms
other than amd64 and ia64. The amd64@ mailing list archive has messages
from users with the same confusion.

We were calling select_a_tag() inside sctp_send_initate_ack().
During collision cases we have a stcb and thus a SCTP_LOCK. When
we call select_a_tag it (below it) locks the INFO lock. We now
1) pre-select the nonce-tie-tags in sctputil.c during setup of
a tcb.
2) In the other case where we have to select tags, we unlock after
incr the ref cnt (so assoc won't go away0 and then do the
tag selection followed by a relock and decr the refcnt.

* Actually use the HAVE_<header>_H macros to conditionally include
system headers. They've been defined for a long time, but only
used in a few places. Now they're used pretty consistently
throughout.
* Fill in a lot of missing casts for conversions from void*.
Although Standard C doesn't require this, some people have been
trying to use C++ compilers with this code, and they do require it.
Bit-for-bit, the compiled object files are identical, except for
one assert() whose line number changed, so I'm pretty confident I
didn't break anything. ;-)
