  Log:
  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).
