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
