collected while scanning is almost certainly out of date

frame and if we get a beacon miss interrupt ignore it if we've received
a frame within the beacon miss interval. This should never trigger
and the handling at the net80211 layer should likewise deal with this
but it doesn't hurt and can suppress extranous probe request frames.
Note that we can legtimately get a bmiss when under heavy load.

New release notes: BIND 9.3.2 (+MFC), IPFilter 4.1.10, tzdata2005r (+MFC).
Deleted release notes: libpcap and tcpdump updates (these updates
were actually a part of 6.0-RELEASE and therefore aren't "new"
anymore).

resolvable in most cases, so administrator will need to change it.
Also do not send our trap messages to 64.15.205.248, use localhost

Rename struct thread's td_sticks to td_pticks, we will need the

Clear td_pticks whenever we enter the kernel instead of recording
its value as reference for userret(). Use the absolute value of
td->pticks in userret() and eliminate third argument.

In the future, we may want to acquire the lock early in the function and
hold it across calls to vn_rdwr(), etc, to avoid multiple acquires.

Keep track of time spent by the cpu in various contexts in units of
"cputicks" and scale to real-world microsec^H^H^H^H^H^H^H^Hclock_t
only when somebody wants to inspect the numbers.
For now "cputicks" are still derived from the current timecounter
and therefore things should by definition remain sensible also on
SMP machines. (The main reason for this first milestone commit is
to verify that hypothesis.)
On slower machines, the avoided multiplications to normalize timestams
at every context switch, comes out as a 5-7% better score on the
unixbench/context1 microbenchmark. On more modern hardware no change
in performance is seen.

a possible hang (or panic if INVARIANTS is on). Previously the accounting
code handled the <= 0 case by calling acctwatch on every clock tick (eww!)
due to an implementation detail of callout_reset(). (Tick counts of
<= 0 are converted to 1).
