freebsd/etc/rc.resume
Nate Lawson 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
