* 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.
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.
* Semantics.
* Remove ACPI_ACAD_DEBUG.
* Reduce the amount of error reporting.
* Remove the internal bookkeeping flags and variables;
instead operate only with a single state variable.
* Trust that the notify handler is doing its job;
remove the refresh routine from the sensor.
* Queue a status check upon resume; we want to know
if the status has changed when in suspend (and it
is unclear if a notify is sent to us).
is discharging; it might make sense when charging, but it doesn't
make sense if neither is the case -- remove a wrong assertion and
arrange the code to make this obvious
(actually, the ACPI spec says that the requirement is only for
rechargeable batteries)
* Remove ACPI_BAT_DEBUG.
* Reduce the amount of error reporting.
* Remove the internal bookkeeping flags.
* Remove the debugging functions used to print status and information
changes. This information is fully conveyed in the output of envstat(8).
* Always evaluate _STA. If it fails or the battery is not present, mark
all remaining sensors as invalid. This will eliminate the convoluted
update routine.
* Semantics.
Over 200 LOC was eliminated, but functional change should again be minimal.

* Provide proper definitions and use these.
* Clarify the evaluation of _STA.
* Mark the state of a sensor according to the return value from _STA.
* Share the basic object evaluation in _BIF and _BST.
* Verify the object types before using the objects.
* Be aware of bogus values from _BIF and _BST, as noted in the
specification.
Despite of the list, functional change should be minimal. Ok pgoyette@.
- Provide the module declaration and use ACPI_FREE
as well as ACPI_ALLOCATE_LOCAL_BUFFER for ACPI_DEBUG.
- Maintain the calling conventions of existing ACPI utility
functions by initializing the output buffer for the caller
in all applicable functions.
- Remove superfluous const correctness. Additional semantics:
u_char -> char, u_int16_t -> uint16_t, and u_int64_t -> uint64_t.
- Collect the validation of input parameters to a single function.

Multiple WMI mapper devices are supported, but each one can have only one
child device.
All exposed functions now require the parent mapper device as a parameter.
