Renumber cluase 4 to 3, per what everybody else did when BSD granted
them permission to remove clause 3. My insistance on keeping the same
numbering for legal reasons is too pedantic, so give up on that point.

This reduces the noise in error reporing from sysctl(8):
Before:
$ sysctl bla=something
sysctl: unknown oid 'bla': No such file or directory
After:
$ sysctl bla=something
sysctl: unknown oid 'bla'

happily return 0 bytes, which isn't too useful or random...

optional attributes field.
- Add a 'machdep.smap' sysctl that exports the SMAP table of the running
system as an array of the ACPI 3.0 structure. (On older systems, the
attributes are given a value of zero.) Note that the sysctl only
exports the SMAP table if it is available via the metadata passed from
the loader to the kernel. If an SMAP is not available, an empty array
is returned.
- Add a format handler for the ACPI 3.0 SMAP structure to the sysctl(8)
binary to format the SMAP structures in a readable format similar to
the format found in boot messages.

Add the following flags to sysctl:
-W - show only writable sysctls
-T - show only tuneable sysctls
This can be used to create a /var/run/sysctl.boot to
compare set tunables versus booted tunables.

reading. (This was already done for writing to a sysctl). This
requires all SYSCTL setups to specify a type. Most of them are now
checked at compile-time.
Remove SYSCTL_*X* sysctl additions as the print being in hex should be
controlled by the -x flag to sysctl(8).

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.

Right now sysctl just prints the major/minor numbers of a device.
Instead of rolling our own routine for this, we'd better just call
devname(3) to perform a translation to a device name for us.
Don't clobber *p with '\0' when testing whether it has the value of 'F'.
Just use the semantics of strtof() properly. If it returns p, we know
that it parsed the string until it reached 'C' or 'F'.
The code has not changed since it has been imported (r161951, Sep 3,
2006).

others. In the case where it displayed warnings it would still return
succesfully. Modify it so that it returns the number of sysctls that
it was not able to set.
Make use of this in rc.d to display only *unsuccessfull* attempts to
set sysctls.
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`.

a warning, return 1 instead of 0 to indicate that we didn't print
anything, so that top-level callers don't print a spurious newline.
This is mainly to fix output formatting when stderr is redirected. It
also helps in some cases when stderr is interleaved with stdout,
depending on the details of the interleaving (this program has the
usual null explicit support for syncing stderr with stdout).
Return 1 instead of -1 after printing the "malloc failed" warning, since
the return value is boolean.

to add a new integer format Q for printing things of type CTLTYPE_QUAD.

such as t_rq, t_dw, t_pw, and t_sw as they are also signed.
