Report I/O stats from the CAM_IOSCHED_DYNAMIC extension

Report, on a periodic basis, the I/O latencies the CAM I/O scheduler
computes. These times are only for the hardware portion of the I/O as
measured from the time the operation is scheduled with the SIM using
xpt_action() until the SIM reports it has completed with xpt_dine(). Any
time the I/O operation spends in a software queue is no included.

The P50 (median), P90, P99 and P99.9 statistics about the latency of
each of the read, write and trim operations that completed during the
polling interval are reported. If there are fewer than 2, 10, 100 or
1000 operations during the polling interval, no statistic is reported
and a single dash '-' is displayed.

The read, write and trim commands (either on the command line or at run
time) toggle display of these operations. The color command toggles
color (it defaults to on, like gstat). When color is enabled, unknown
statistics are reported in blue, high latency for a statistics is
reported in red, medium in magenta and low in green (as with gstat). The
med= and hi= commands can set these latency thresholds.

Limitations: The entire sysctl space for all the devices is walked for
each polling period. This should be optimized to remember the OIDs and
only do such polling with the xpt generation changes. There is also no
way to filter devices displayed. This command only works on physical
devies that are connected to SCSI, ATA or NVME sims as those are the
only ones that are instrumented in the CAM I/O scheduler (the
CAM_IOSCHED_DYNAMIC option must be in the kernel, and the dynamic
scheduler can't be disabled).

Augment systat(1) -swap to display large swap space processes

This change updates the systat(1) -swap display to use libprocstat to
obtain and display per-process swap space usage infomation following its
existing swap devise/file statistics. It also incorporates the disk I/O
information from the -vmstat display.

The new screen looks like below with 'systat -swap':

* 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`.

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.

Update for moving some fields to the new vnstat display.

Don't say that `cache' is for the buffer cache.

Describe the uselessnes of `buf'.

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.

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.

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.
