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).

systat: mostly clean up warns

Sponsored by: Rubicon Communications, LLC ("Netgate")

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':

systat: use and correctly display 64bit counters.

Following struct vmtotal changes, make systat use and correctly
display 64-bit counters. Switch to humanize_number(3) to overcome
homegrown arithmetics limits in pretty printing large numbers. Use
1024 as a divisor for memory fields to make it consistent with other

Bump WARNS level to 1

Convert to usr.bin/ to LIBADD
Reduce overlinking

Revert r261296. This removes the WITHOUT_NCURSESW option.

It was the wrong direction. We will instead remove use of the
non-wide-character supporting libncurses.

Use src.opts.mk in preference to bsd.own.mk except where we need stuff
from the latter.

Nuke "systat -mbuf". It was broken since FreeBSD 5, and since there
haven't been any complaints, no one used it.

A new jail(8) with a configuration file, to replace the work currently done
by /etc/rc.d/jail.

Create the altix project branch. The altix project will add support
for the SGI Altix 350 to FreeBSD/ia64. The hardware used for porting
is a two-module system, consisting of a base compute module and a
CPU expansion module. SGI's NUMAFlex architecture can be an excellent
platform to test CPU affinity and NUMA-aware features in FreeBSD.

Fixed dependencies (make checkdpadd).

Perform all trivial ports to utmpx for usr.bin/.

They were already converted to use libulog, so it's easy to convert them
to utmpx.

Build usr.bin/ with WARNS=6 by default.

Also add some missing $FreeBSD$ to keep svn happy.

Let systat's vmstat use utmpx.

Backout sensors framework.

Requested by: phk
Discussed on: cvs-all

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`.

Back out rev. 1.17: arch-dependent WARNS level.

The policy is that the WARNS level should characterize the
quality of a piece of code irrespective of any conditions.
Otherwise the code doesn't deserve the WARNS level assigned.

Requested by: ru

systat(1) reaches WARNS=6 on i386 and amd64. This is good
for catching general regressions in future. Unfortunately,
it still displays some problems at WARNS=6 on architectures
with stricter alignment requirements, e.g., ia64.

Obey MK_INET6_SUPPORT.

Put libdevstat before libkvm, because the former depends on the latter.

Add ip6 and icmp6 displays to systat.

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.

Remove NO_WERRORs and WARNS=n's. To be revisited after GCC3.

WARNS=2 fixes with NO_WERROR set, as there are some header issues
with namelists. use __FBSDID().

Removed -I${.CURDIR}/.../sys from CFLAGS.

Get rid of setgid kmem for systat, and while being there, fix some bugs
and compiler warnings.
The data for network statistics are still obtained via the kvm interface
if systat was started with the needed privileges, otherwise sysctls are
used. The reason for this is that with really many open sockets, the
sysctl method is probably slower, but it systat -netstat is probably not
really usable in either mode under these conditions.
