00a304487f Update the suspend/resume user API while maintaining backwards compat.
Improvements:
* /etc/rc.suspend,rc.resume are always run, no matter the source of the
  suspend request (user or kernel, apm or acpi)
* suspend now requires positive user acknowledgement.  If a user program
  wants to cancel the suspend, they can.  If one of the user programs
  hangs or doesn't respond within 10 seconds, the system suspends anyway.
* /dev/apm is clonable, allowing multiple listeners for suspend events.
  In the future, xorg-server can use this to be informed about suspend
  even if there are other listeners (i.e. apmd).

Changes:
* Two new ACPI ioctls:  REQSLPSTATE and ACKSLPSTATE.  Request begins the
  process of suspending by notifying all listeners.  acpi is monitored by
  devd(8) and /dev/apm listener(s) are also counted.  Users register their
  approval or disapproval via Ack.  If anyone disapproves, suspend is vetoed.
* Old user programs or kernel modules that used SETSLPSTATE continue to
  work.  A message is printed once that this interface is deprecated.
* acpiconf gains the -k flag to ack the suspend request.  This flag is
  undocumented on purpose since it's only used by /etc/rc.suspend.  It is
  not intended to be a permanent change and will be removed once a better
  power API is implemented.
* S5 (power off) is no longer supported via acpiconf -s 5 or apm -z/-Z.
  This restores previous behavior of halt/shutdown -p being the interface.
* Miscellaneous improvements to error reporting

88a86dedce Make sure pid file creation doesn't complain if it can't create the file.
This removes a warning message when suspending is called by a non-root
user.

e776370e2b Add support for /etc/rc.suspend and /etc/rc.resume for ACPI. They are
called directly from acpiconf(8).  Change both scripts to take a
subsystem (apm|acpi) and sleep level (suspend,standby|1-5) argument.

a1c43e3fbb Add copyright notices. Other systems have been barrowing our /etc files
w/o giving any credit.

321704296f Apply a consistent style to most of the etc scripts. Particularly, use
case instead of test where appropriate, since case allows case is a sh
builtin and (as a side-effect) allows case-insensitivity.

Changes discussed on freebsd-hackers.
