24072ca35b - Move timerreg.h to <arch>/include and split i8253 specific defines into 
i8253reg.h, and add some defines to control a speaker.
- Move PPI related defines from i386/isa/spkr.c into ppireg.h and use them.
- Move IO_{PPI,TIMER} defines into ppireg.h and timerreg.h respectively.
- Use isa/isareg.h rather than <arch>/isa/isa.h.

Tested on: i386, pc98

fdace17f81 Fix for a bug where the "nexthole" sack hint is out of sync with the 
real next hole to retransmit from the scoreboard, caused by a bug
which did not update the "nexthole" hint in one case in
tcp_sack_option().

b3cf6808ce In div_output() explicitly set m->m_nextpkt to NULL. If divert socket 
is not userland, but ng_ksocket, then m->m_nextpkt may be non-NULL. In
this case we would panic in sbappend.

0f4a3524dd When used as divert socket we need to decouple stack when node is entered 
from socket side. Use ng_queue_fn() instead of ng_send_fn().

0077b0163f When looking for the next hole to retransmit from the scoreboard, 
or to compute the total retransmitted bytes in this sack recovery
episode, the scoreboard is traversed. While in sack recovery, this
traversal occurs on every call to tcp_output(), every dupack and
every partial ack. The scoreboard could potentially get quite large,
making this traversal expensive.

This change optimizes this by storing hints (for the next hole to
retransmit and the total retransmitted bytes in this sack recovery
episode) reducing the complexity to find these values from O(n) to
constant time.

The debug code that sanity checks the hints against the computed
value will be removed eventually.

494e177ada A new version of NetFlow node. 
The most significant changes are:
- Use UMA zone instead of own chunk of memory.
- Lock each hash entry separately.
- Expire items "actively" - interrupt method can expire flows
  from hash slot, when it searches through it.
- Remove global tailqueue. Make callout thread search through
  every hash slot.
- Export datagram is detached from private data and filled. If
  it is incomplete, it is attached back. Another thread will
  continue working with it.

Lesser, but also important speedups:
- Flows in hash slot are stored in tailqueue. Whenever a flow is
  hit, it is moved to the begging, so it can be located quicker.
- When callout thread works with hash slot it bails out if
  slot mutex is contested.
