- Now that apm loadable module can inform its existence to other kernel
components (e.g. i386/isa/clock.c:startrtclock()'s TCS hack).
- Exchange priority of SI_SUB_CPU and SI_SUB_KLD for above purpose.
- Add simple arbitration mechanism for APM vs. ACPI. This prevents
the kernel enables both of them.
- Remove obsolete `#ifdef DEV_APM' related code.
- Add abstracted interface for Powermanagement operations. Public apm(4)
functions, such as apm_suspend(), should be replaced new interfaces.
Currently only power_pm_suspend (successor of apm_suspend) is implemented.

- Add a new MIB for battery info expire time in order to make it changeable.
Battery info expire time can be specified by
hw.acpi.battery.info_expire in sec.
- Add own MALLOC type and fix some potential memory leakages.
- Change some frequent printings to verbose printing.
- Stop timeout during acpi_cmbat_get_bst() too. This should reduce
the races with BIF evaluation.
- Remove acpi_cmbat_get_bif() invocation from acpi_cmbat_attach().
This was redundant because this should be called from
acpi_cmbat_timeout() now.
- Give a guaranteed minimum cooling run time to avoid too frequent
cooling system On/Off switching. The minimum cooling run time can be
specified by hw.acpi.thermal.min_runtime in sec.
- Refine message printing (_AC-1 -> NONE).
- Add verbose mode enable/disable capability by hw.acpi.verbose in bool.

- Remove TASK_DESTROY now that it is no longer needed.
- Go back to inlining TASK_INIT now that it is short again.

This emulates APM device node interface APIs (mainly ioctl) and
provides APM services for the applications. The goal is to support
most of APM applications without any changes.
Implemented ioctls in this commit are:
- APMIO_SUSPEND (mapped ACPI S3 as default but changable by sysctl)
- APMIO_STANDBY (mapped ACPI S1 as default but changable by sysctl)
- APMIO_GETINFO and APMIO_GETINFO_OLD
- APMIO_GETPWSTATUS
With above, many APM applications which get batteries, ac-line
info. and transition the system into suspend/standby mode (such as
wmapm, xbatt) should work with ACPI enabled kernel (if ACPI works well :-)

visible change is that a TASK_DESTROY() macro has been added to mirror
the TASK_INIT() macro to destroy a task before it is free'd.

Use acpi_DeviceIsPresent in acpi_pcib rather than rolling our own

This should solve the problem where devices that have been disabled eg. in

This is functionally equivalent to teh previousl -current except
