  Log:
  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
