Update module dependencies for all the existing modules that depend on sysmon components.

Always explicitly enable the wake GPE for acpibut(4). This follows FreeBSD
and Linux, although it is somewhat unclear why this is necessary. But better
safe than sorry.

Use ioconf for the module declarations.

branches: 1.39.2; 1.39.4;
Bump WARNS to 4.

Bypass ACPI_NOTIFY_DEVICE_WAKE also in acpilid(4). Use aprint_debug_dev(9)
for an unknown notify. (The ACPI drivers should really not print anything
as we now have a global notify handler that can catch the debug information.)

in acpibut_notify_handler, suppress 'unknown event' messages for
ACPI_NOTIFY_DEVICE_WAKE. Control method power and sleep buttons can
generate this event upon waking from G1 sleep to indicate that it was
responsible for waking the system.

Use ACPICA's standard notify values from <actypes.h> and move the
device-specific notify constants to the device-specific files.

As discussed with jmcneill@, install a global "bus notification handler"
that receives all notifications and deliver notifications to drivers via it.

branches: 1.34.2;
Remove <dev/acpi/acpica.h> from all files. It is included from
<dev/acpi/acpivar.h>. Ditto for <dev/sysmon/sysmonvar.h>, <sys/bus.h>,
<dev/pci/pcivar.h>, and <dev/isa/isavar.h>.

Also nuke a lot of unused and invalid headers. Some of these are audibly
provided by standard headers (namely <sys/param.h> and <sys/device.h>), some
have nothing to do with ACPI devices (e.g. <sys/syslog.h>), and some are
nonexistent local includes (e.g. "mpu_ym.h"). Moreoever, try to group the
includes into their respective blocks.

Tested with GENERIC and ALL (i386). No functional change.

Add missing semicolon.

Cleanup:

* Semantics.
* No need for <dev/acpi/acpica.h>.
* Reduce the amount of error reporting.
* Remove ACPI_BUT_DEBUG and ACPIBUT_F_VERBOSE.

No functional change.

Introduce support for ACPI kernel modules.

Tested on couple of laptops.

branches: 1.30.2;
Add detachment routines.

Add the _COMPONENT definition for ACPI_DEBUG.

PR# kern/41179: Incorrect return values from AcpiOsExecute()

ACPICA functions return ACPI_STATUS instead of int, so use it for
consistency.

add hw.wake.* sysctl subtree for toggling which devices are allowed to
restore the system from sleep. set/clear wake GPEs as specified before
entering sleep.

by default, the following devices are enabled for wake:
- sleep/power buttons
- lid switch
- pc kbd controller

specify static where appropriate.

split power button and sleep button HIDs so that they can be matched
against compatibility IDs.

return (x) -> return x
use consitent variable name for ACPI_STATUS

More cleanup:
* Use ACPI_FAILURE() and ACPI_SUCCESS().
* Output exception strings in a few more places.

Clean up some messages:
* Use AcpiFormatException() in a bunch of places.
* acpi_resource_parse() already prints an error, so don't do it in the callers.

* now the size of ACPI_DEVICE_INFO is variable:
it can now accomodate multiple _CIDs
sizeof(ACPI_DEVICE_INFO) should not be used
* make ad_devinfo member in acpi_devnode a pointer
* implement acpi_match_hid() to simplify matching devices;
_CIDs are also taken into account now as well as _HID

Catch up with ABI changes in ACPI-CA. Some additional changes to acpi_bat to
set the VALID bits correctly, so we don't report garbage for missing batteries.

branches: 1.9.2;
* Add a generic power management event API, defined in <sys/power.h>.
Right now, only power switch state change events are supported. This
is a work-in-progress.
* Add support to sysmon for delivering power mangement events to userland.
Add poll, kqueue, and read entry points to sysmon.
* Adapt ACPI to use the new generic <sys/power.h> event types.

This provides the kernel support for a forthcoming powerd(8) which can
do nice things like gracefully shut the system down when an ACPI power
button is pressed.

Oops, remove a debugging define.

* Don't do the ACPI_PCI_FIXUP unless it is explicitly enabled in
the kernel config file. That code makes a total mess of any
system with multiple PCI busses.
* Rework the way buttons are handled; register them with sysmon,
and let it take the appropriate action. This lets us gracefully
shut down when the power button is pressed.

Add trailing ; to CFATTACH_DECL.
