Make Tflag and Wflag filters work for more sysctl options.

To do this move the Tflag and Wflag checks earlier in show_var() so
we bail earlier for variables not matching our query.

Allow sysctl to filter boot and runtime tunables.

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

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

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

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).

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`.

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.

Some improvements to the int-type printing code based on suggestions by bde.

Fix a number of WARNS, including printf, constness and unsigned comparison
warnings.

Some style improvements suggested by bde, including removing an
unused include, adding parens for return and sizeof and renaming,
adding some missing whitespace and sorting some variables.
