fd7356a917 Convert socket options code to use a sockopt structure 
instead of laying everything into an mbuf.

c5ddeafa76 Unlock reassembly queue before calling sorwakeup(), not after. In unusual 
cases with in-kernel consumers which might send data on the same socket,
we can deadlock on the reassembly queue otherwise (observed while testing
accept filters).

717f903a98 Add accept filters, ported from FreeBSD by Coyote Point Systems. Add inetd 
support for specifying an accept filter for a service (mostly as a usage
example, but it can be handy for other things).  Manual pages to follow
in a day or so.

OK core@.

e071d39c84 - Convert hashinit() to use kmem_alloc(). The hash tables can be large 
and it's better to not have them in kmem_map.
- Convert a couple of minor items along the way to kmem_alloc().
- Fix some memory leaks.

15e29e981b Merge the socket locking patch: 
- Socket layer becomes MP safe.
- Unix protocols become MP safe.
- Allows protocol processing interrupts to safely block on locks.
- Fixes a number of race conditions.

With much feedback from matt@ and plunky@.

04e54b2ef5 - ipflow is not used outside ip_flow.c; move its definition there. 
- Make ipflow_reap() private to ip_flow.c, and introduce ipflow_prune()
  for external callers to use (avoids returning an ipflow * that is never
  actually used anyway).

564b60af35 - Make sure we send a reasonable fragment size when IPSEC is configured. 
Otherwise we end up sending a dubious "0" whenever we cannot find a
  proper association for the packet.
- Reset sack_newdata along with snd_nxt to avoid improper integer
  arithmetics that lead to sending data from an incorrect place in the
  stream, making it appear as corrupted.

Patch by Michael Van Elst, based on an analysis by Michael for the IPSEC
stuff and I for the SACK issue.

c6186face4 Welcome to 4.99.55: 
- Add a lot of missing selinit() and seldestroy() calls.

- Merge selwakeup() and selnotify() calls into a single selnotify().

- Add an additional 'events' argument to selnotify() call.  It will
  indicate which event (POLL_IN, POLL_OUT, etc) happen.  If unknown,
  zero may be used.

Note: please pass appropriate value of 'events' where possible.
Proposed on: <tech-kern>

a34217b8de Rework tcp congctl selection code so that the congctl entries can be const. 
Don't access tcp_congctl stuff outside of tcp_congctl.c, use routines to
update t_congctl.  This code is slightly now more complicated.
