* Serialize acpi_battery_get_battdesc(), acpi_battery_register(), and
  acpi_battery_remove().
* Assert that the sx lock is held in acpi_batteries_init().
* Remove check for device_get_softc() returning NULL.

7a5230b8ad Add the ability to detach a battery. Now batteries that are detached are
also removed from the battery list.

remove unused includes.

9febbb4078 Some improvements of control method battery driver.
- 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.

f86214b6b8 Add APM compatibility feature to ACPI.
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 :-)
