9079fff550 Align the interfaces for the various watchdogs and make the interface
behave as expected.

Also:
- Return an error if WD_PASSIVE is passed in to the ioctl as only
  WD_ACTIVE is implemented at the moment. See sys/watchdog.h for an
  explanation of the difference between WD_ACTIVE and WD_PASSIVE.
- Remove the I_HAVE_TOTALLY_LOST_MY_SENSE_OF_HUMOR define. If you've
  lost your sense of humor, than don't add a define.

Specific changes:

i80321_wdog.c
  Don't roll your own passive watchdog tickle as this would defeat the
  purpose of an active (userland) watchdog tickle.

ichwd.c / ipmi.c:
  WD_ACTIVE means active patting of the watchdog by a userland process,
  not whether the watchdog is active. See sys/watchdog.h.

kern_clock.c:
  (software watchdog) Remove a check for WD_ACTIVE as this does not make
  sense here. This reverts r1.181.

724f57b2a3 Yield to ru's ninja-like manpage skills and update watchdog(4) to
look more like other manpages. Move some content around, use an EXAMPLES
section, etc.

e35b01929d Fix up a little language. Remove reference to sysctl(9). Fix reference to
watchdog(9) (was watchdogd(9)).

4103b7652d Rename the WATCHDOG option to SW_WATCHDOG and make it use the
generic watchdoc(9) interface.

Make watchdogd(8) perform as watchdog(8) as well, and make it
possible to specify a check command to run, timeout and sleep
periods.

Update watchdog(4) to talk about the generic interface and add
new watchdog(8) page.

370c3cb57c - Add a software watchdog facility.
This commit has two pieces. One half is the watchdog kernel code which lives
primarily in hardclock() in sys/kern/kern_clock.c. The other half is a userland
daemon which, when run, will keep the watchdog from firing while the userland
is intact and functioning.
