Additional detach implementaions (or maybe improvement) for other

c02106f3cc Add a locking stub to call acpi_cmbat_get_bif() now that it is directly
run from the taskqueue.  There should probably be a better way to do this
later, but this suffices for now.

2010798dab Try to fix problems with periodic hangs by never directly calling _BIF.
Instead, re-evaluate _BIF only when we get a notify and use the cached
results.  We also still evaluate _BIF once on boot.  Also, optimize the
init loop a little by only querying for a particular info if it's not valid.

76f6fe4f31 Rewrite the acpi_battery interface to allow for other battery types
(i.e., smart battery) and fix various bugs found during the cleanup.

API changes:
* kernel access:
Access to individual batteries is now via devclass_find("battery").
Introduce new methods ACPI_BATT_GET_STATUS (for _BST-formatted data) and
ACPI_BATT_GET_INFO (for _BIF-formatted data).  The helper function
acpi_battery_get_battinfo() now takes a device_t instead of a unit #
argument.  If dev is NULL, this signifies all batteries.

* ioctl access:
The ACPIIO_BATT_GET_TYPE and ACPIIO_BATT_GET_BATTDESC ioctls have been
removed.  Since there is now no need for a mapping between "virtual" unit
and physical unit, usermode programs can just specify the unit directly and
skip the old translation steps.  In fact, acpiconf(8) was actually already
doing this and virtual unit was the same as physical unit in all cases
since there was previously only one battery type (acpi_cmbat).  Additionally,
we now map the ACPIIO_BATT_GET_BIF and ACPIIO_BATT_GET_BST ioctls for all
batteries, if they provide the associated methods.

* apm compatibility device/ioctls:  no change
* sysctl:  no change

Since most third-party applications use the apm(4) compat interface, there
should be very few affected applications (if any).

a0885d3f14 Notify the user when the battery is critically low. In the future, we
may want to shut down here but the chance of BIOS vendors getting this
wrong is high.  They're only supposed to announce this when all batteries
hit their critical level but past experience indicates we should be
conservative about this for now.

4c37803a89 Fix a deadlock on boot for some systems where reading the battery status

* Serialize ops in acpi_cmbat_notify_handler(), acpi_cmbat_ioctl(),
  acpi_cmbat_init_battery(), and acpi_cmbat_get_battinfo().
* Get the softc directly in acpi_cmbat_get_total_battinfo() rather than
  build an array of them.
* Don't queue a _BIF query after receiving a notify.  Since we clear the
  timespec, a _BIF query will be done in the context of the next caller.
* Add asserts to leaf functions that operate on shared data.
* Remove the bst/bif updating flags now that we hold the lock over the
  full query.

9b7b2aeff6 Some laptops report the "design-capacity" instead of the "real-capacity"
when the battery is fully charged. That breaks some of the arithmetic in
calculating the remaining capacity (ends up with more than 100%).
This commit makes sure the max is 100.

9123341378 Add support to ACPI to manage its own resources. Previously, resource
allocation was passed up to nexus.  Now, we probe sysresource objects and
manage the resources they describe in a local rman pool.  This helps
devices which attach/detach varying resources (like the _CST object) and
module loads/unloads.  The allocation/release routines now check to see if
the resource is described in a child sysresource object and if so,
allocate from the local rman.  Sysresource objects add their resources to
the pool and reserve them upon boot.  This means sysresources need to be
probed before other ACPI devices.

Changes include:
* Add ordering to the child device probe.  The current order is:  system
resource objects, embedded controllers, then everything else.
* Make acpi_MatchHid take a handle instead of a device_t arg.
* Replace acpi_{get,set}_resource with the generic equivalents.

595a08978c Match namespace cleanup changes in ACPI CA 20020217 update.
Use ACPI_SUCCESS/ACPI_FAILURE consistently.
The AcpiGetInto* interfaces are obsoleted by ACPI_ALLOCATE_BUFFER.

Kill off the timeouts that used to read _BIF and _BST.  These are
invoked when the battery is actually read.  timeout() is dangerous
in combination with ACPI, as the interpreter can block.

This driver still needs more work.

c573e654b7 Add OS layer ACPI mutex and threading support.
- Temporary fix a bug of Intel ACPI CA core code.
 - Add OS layer ACPI mutex support.  This can be disabled by
   specifying option ACPI_NO_SEMAPHORES.
 - Add ACPI threading support.  Now that we have a dedicate taskqueue for
   ACPI tasks and more ACPI task threads can be created by specifying option
   ACPI_MAX_THREADS.
 - Change acpi_EvaluateIntoBuffer() behavior slightly to reuse given
   caller's buffer unless AE_BUFFER_OVERFLOW occurs.  Also CM battery's
   evaluations were changed to use acpi_EvaluateIntoBuffer().
 - Add new utility function acpi_ConvertBufferToInteger().
 - Add simple locking for CM battery and temperature updating.
 - Fix a minor problem on EC locking.
 - Make the thermal zone polling rate to be changeable.
 - Change minor things on AcpiOsSignal(); in ACPI_SIGNAL_FATAL case,
   entering Debugger is easier to investigate the problem rather than panic.

 - 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.
