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.)

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.

No need to spread the ACPICA type system any more than is necessary:

UINT8 -> uint8_t and UINT32 -> uint32_t.

branches: 1.37.2;
Preparing a device for wakeup involves:

(a) turning on all power resources required by the device; and
(b) executing _DSW (or _PSW) control method.

This implements (b). Ok jmcneill@.

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.

Introduce support for ACPI kernel modules.

Tested on couple of laptops.

Cleanup:

* Semantics.
* Remove ACPI_LID_DEBUG.
* Reduce the amount of error reporting.
* As the status of the lid (open/closed) is known upon suspend, move the
state variable to the softc, and avoid one object evaluation this way.

A pointer typedef entails trading too much flexibility to declare const
and non-const types, and the kernel uses both const and non-const
PMF qualifiers and device suspensors, so change the pmf_qual_t and
device_suspensor_t typedefs from "pointers to const" to non-pointer,
non-const types.

branches: 1.32.2;
Add the _COMPONENT definition for ACPI_DEBUG.

Expand PMF_FN_* macros.

As the _PSW control method was deprecated in ACPI 3.0, augment the wake
event call with the newer _DSW control method.

ok pgoyette@, jmcneill@

Introduce acpi_eval_set_integer().
Use it in various acpi drivers to simplify code.

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

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

Make it compile (int -> ACPI_INTEGER)

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: 1.8.2;
* 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.

Adapt to the sysmon_pswitch interface.

Add trailing ; to CFATTACH_DECL.
