Copy head to stable/9 as part of 9.0-RELEASE release cycle.

Approved by: re (implicit)

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.

Use ncursesw to output the date field of vmstat display
with multi-byte string, correctly.

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.

MFC after: 2 weeks

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.

Remove unneded -ltermcap

Reference new files for device stat support.

Having done ICMP, UDP, and IP, could a TCP display be far behind?

Emboldened by the success of yesterday's ICMP statistics display,
I've now added one that does IP (and also UDP) statistics.

Add a mode to display ICMP statistics.

Inspired by: IRIX netstat -C

Fixed DPADD.

Another absolute path...
