Fix typo and bump date.

The kernel is not exporting any "T,dev_t" sysctl nodes anymore, so
remove the capability and mention from sysctl(8).

Add the -i option to the synopsis.

Implement the "-i" option to sysctl(8), to ignore failures while
retrieving individual OIDs. This allows the same list of OIDs to be
passed to sysctl(8) across different systems where particular OIDs may not
exist, and still get as much information as possible from them.

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`.

rev.1.42 -- i do not think it is appropriate to put the full
description in this manpage, and the "boot" and "loader" manpages
where this description might go are also missing a description of
a number of similar variables, so i think this it is ok to limit
documentation to this now, and update it later when I (or someone
else) have a chance to revise "boot" and "loader".

- Attempt to help declutter kern. sysctl by moving security out from

Reviewed by: rwatson

Add code to export and print the description associated to sysctl
variables. Use the -d flag in sysctl(8) to see this information.

Possible extensions to sysctl:
+ report variables that do not have a description
+ given a name, report the oid it maps to.

Note to developers: have a look at your code, there are a number of
variables which do not have a description.

Note to developers: do we want this in 4.5 ? It is a very small change
and very useful for documentation purposes.

Implement -e option. It modifies the output produced by sysctl(8) in
such a way that the name and the value of the variable(s) are separated
with `=' instead of the usual `: '. This is useful for producing output
that can be fed back to the sysctl utility (pasted to sysctl.conf, for
example).

Document the deprecated `-w' option in the COMPATIBILITY section.

Since the ``-w'' sysctl(8) option has been deprecated,
don't mention it in the manpages.

Remove xref to blackhole(4). sysctl has nothing to do with
blackhole(4), except that blackhole(4) uses sysctl's. This xref
obviously isn't appropriate unless we want to xref all the other man
pages which mention sysctls, which we obviously don't (we may want to
list those sysctls, but that's another story).

Update the document date after DES's updates, move the description of
the -b option below -a to maintain alphabetical order, and add a
missing ".It" before "Fl o".

Try to make sysctl options slightly more orthogonal:

- introduce a -o option that displays opaque variables.
- introduce a -x option that displays opaque variables in full.
- deprecate -A in favor of -ao and -X in favor of -ax.
- remove -A and -X from usage() and SYNOPSIS (but not from DESCRIPTION).
- ignore -a if one or more variables were listed on the command line.
- deprecate -w, it is not needed to determine the user's intentions.
- some language and style cleanup in the man page.

This commit should not break any existing scripts.

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.

Removed references to pathconf-related variables that were never handled
by sysctl and never can be in their documented form (kern.name_max would
have to become fs.filesystemname.name_max, etc.).

Added missing references to user.stream_max and user.tzname_max. These
seem to misnamed. <sys/sysconf.h> says that they correspond to POSIX2
names, but the sysconf names don't have POSIX2 or "posix2" like all the
other POSIX2 names.

Use the .Fx macro where appropriate.

Fix a bunch of spelling errors in a bunch of man pages.

The rewamped sysctl program that will find all the variables itself.
Also a couple of handy new options.

Implement maxprocperuid and maxfilesperproc. They are tunable
via sysctl(8). The initial value of maxprocperuid is maxproc-1,
that of maxfilesperproc is maxfiles (untill maxfile will disappear)

Now it is at least possible to prohibit one user opening maxfiles
