8a05965c77 Only print the errno string in case sysctl(3) does not file with ENOENT
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'

9d531dc3c1 - Add a new structure type for the ACPI 3.0 SMAP entry that includes the
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.

6648b8cede sysctl(8) should use the CTLTYPE to determine the type of data when
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).

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.

that it parsed the string until it reached 'C' or 'F'.

4af9918bc0 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`.

0911a23bee When we return from a "show" function without printing anything except
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.

3b8270a3d5 - Revert signedness type changes to "struct vmtotal"; by making
them unsigned I made the possible overflows hard to detect,
  and it only saved 1 bit which isn't principal, even less now
  that the underlying issue with the total of virtual memory has
  been fixed.  (For the record, it will overflow with >=2T of
  VM total, with 32-bit ints used to keep counters in pages.)

- While here, fix printing of other "struct vmtotal" members
  such as t_rq, t_dw, t_pw, and t_sw as they are also signed.
