99f6b270e3 Import OpenBSD's sysctl hardware sensors framework.
This commit includes the following core components:

 * sample configuration file for sensorsd
 * rc(8) script and glue code for sensorsd(8)
 * sysctl(3) doc fixes for CTL_HW tree
 * sysctl(3) documentation for hardware sensors
 * sysctl(8) documentation for hardware sensors
 * support for the sensor structure for sysctl(8)
 * rc.conf(5) documentation for starting sensorsd(8)
 * sensor_attach(9) et al documentation
 * /sys/kern/kern_sensors.c
   o sensor_attach(9) API for drivers to register ksensors
   o sensor_task_register(9) API for the update task
   o sysctl(3) glue code
   o hw.sensors shadow tree for sysctl(8) internal magic
 * <sys/sensors.h>
 * HW_SENSORS definition for <sys/sysctl.h>
 * sensors display for systat(1), including documentation
 * sensorsd(8) and all applicable documentation

The userland part of the framework is entirely source-code
compatible with OpenBSD 4.1, 4.2 and  -current as of today.

All sensor readings can be viewed with `sysctl hw.sensors`,
monitored in semi-realtime with `systat -sensors` and also
logged with `sensorsd`.

04984aac91 For the vmstat sub-display:
vmstat.c:
Move totfr to be under daefr and prcfr since it logically belongs there.

Move all the count fields (wire, act, inact, cache and free) to near
the bottom of the sub-display (after all the rate fields) to reduce
competition with adjoining sub-displays.

systat.1:
Move things as above.

Attempt to improve missing and poor wording in the description of the
fields.  The long sentence was hard to parse and didn't say anything
about the different units.

Increment .Dd.

b16f944633 Removed the description of the nonexistent want_fd command. want_fd existed
for only 2 weeks in 1998-1999.  It was replaced by general commands to
select the set of disk drives displayed.

6e977072c6 Fix "slow (on-the-fly) zero fills percentage (`%slo-z')" some more. The
value printed is actually the optimized (i.e., the non-slow, not-on-the-fly
zero fills percentage) except in overflow cases.  Describe it as %ozfod
in the display.  Move the field descriptor 1 to the left so that there
is space for 5 characters after the % sign (this leaves no space between
the number and the descriptor but the % character serves well as a
separator).

Fixed integer overflow at z.ozfod = UINT_MAX/100 in the calculation of
%ozfod.  This value can be reached just a few hours or minutes after
booting, so %ozfod was usually garbage in boot mode.  Now %ozfod is
correct in boot mode for a few days or hours.

Print a non-dummy %ozfod when the division for it isn't division by 0
instead of when the result will be less than 100%.  A result of 100%
may be correct, though a result of more than 100% indicates overflow
of one or both counters.

e76bdda079 Abbreviate long field descriptors at write time so that they don't get
clobbered at runtime:
    dirtybuf -> dtbuf
    desiredvnodes -> desvn
    numvnodes -> numvn
    freevnodes -> frevn
The vmstats column has only 5 characters available for descriptors, but up
to 13 were used.  The extras get clobbered at runtime by interrupt values
and/or descriptors on systems with more than 12 interrupt sources.
    %slo-z -> %sloz
This one is in the "extended" vmstats area and doesn't get clobbered now.

Removed stale documentation of desvn.

Changed a descriptor:
    tfree -> totfr
so that it is consistent with the abbreviations for other free counts
(daefr and prcfr) and thus almost decodeable.

Fixed missing documentation of tfree/totfr.  This and everything else
in the extended vmstats area is misdocumented as being in a certain
place in the vmstats column.

b59ba7df87 Add "ifstat" display:
ifstat      Display the network traffic going through active interfaces
                 on the system.  Idle interfaces will not be displayed until
                 they receive some traffic.

                 For each interface being displayed, the current, peak and
                 total statistics are displayed for incoming and outgoing
                 traffic.  By default, the ifstat display will automatically
                 scale the units being used so that they are in a human-read-
                 able format.  The scaling units used for the current and peak
                 traffic columns can be altered by the scale command.

3be5f1f5ce Add $Id$, to make it simpler for members of the translation teams to
track.

The $Id$ line is normally at the bottom of the main comment block in the
man page, separated from the rest of the manpage by an empty comment,
like so;

     .\"    $Id$
     .\"

If the immediately preceding comment is a @(#) format ID marker than the
the $Id$ will line up underneath it with no intervening blank lines.
Otherwise, an additional blank line is inserted.
