constants in acpidump.h.
- Verify the extended checksum on the RSDP.
- Handle new ACPI 3.0 fields in MADT including X2APIC entries and
UIDs for local SAPICs.
- Add handling for new ACPI 3.0 flags in the FADT.

Until the code is cleaned up, just add -fno-strict-aliasing to the
CFLAGS of these for the tinderboxes' sake, allowing the rest of the
tree to have -Werror enabled again.
variable bug that's hidden by the precense of the hint_acpi_0_rsdp
hint on 386 and amd64. There's never a need for such hint on ia64.

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

my patches for this information. Commit my more complete version.
This version isn't complete yet, since some details aren't handled
right just yet.
