6b5f615b7c Introduce signed and unsigned version of CTLTYPE_QUAD, renaming
existing uses.  Rename sysctl_handle_quad() to sysctl_handle_64().

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).

e367b167d9 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.

104d85906c Just use devname(3) to print device names.
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.

5598d561ce Make input parsing in Farhenheit actually work.
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).

5b37d9eba7 The sysctl(8) program exits on some errors and only emits warnings on
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.

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.

79a4f2f433 Use common code for printing ints and longs by coppying the sysctl
value into a variable of the right type and then printing it via
an intmax_t. This makes avoids some duplication and makes it easy
to add a new integer format Q for printing things of type CTLTYPE_QUAD.

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.

a91c39740f While convenient, avoid using alloca() for reasons specified in
the BUGS section of the alloca(3) manpage.  In particular, when
the number of TCP sockets is several tens of thousand, trying to
"sysctl -a" would SIGSEGV on the net.inet.tcp.pcblist entry (it
would exceed the stacksize ulimit, in an undetectable manner).
