Reencode files to UTF-8. Drop CP1252 em-dash.

Fixed the misplaced $FreeBSD$.

Remove the ACPIIO_ENABLE and ACPIIO_DISABLE ioctls as well as all
callers. These ioctls attempted to enable and disable the ACPI
interpreter at runtime. In practice, it is not possible to boot with
ACPI and then disable it on many systems and trying to do so can cause
crashes, interrupt storms, etc. Binary compatibility with userland is
retained.

MFC after: 2 days

Markup nit: make the list of options look better.

I don't normally use my middle name, so remove it from attributions in
man pages (though not from copyright notices). While I'm here, add email
addresses where appropriate.

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.

Add the -i flag to acpiconf(8) to retrieve battery information.
Rename a few structure elements.

Allow sleep states to be specified as S1, S2, ...
This is used by zzz(8).

mdoc(7) police: markup fixes.

Approved by: re

Add sleep state explanation.
Requested by: murray at Cafe in Tokyo.

The .Nm utility

ACPI CA doesn't recognis S4BIOS as a seperate sleep type anymore, so
drop support for it here until we work out a better way of handling it.

Remove whitespace at EOL.

mdoc(7) police: .Dv -> .Cm where appropriate.

Spell my name right in the copyright.

Oops, forgotten to add manpage.
