Cleanups and support code for importing smart battery support.

* Use ACPI_BATT_UNKNOWN instead of constants
* Use maxunit instead of a count of devices since we may have sparse
  battery devices in the future.  Only userland should be using unit
  numbers anyway, so provide a translation function.  (Kernel use of
  batteries should be restricted to looking up a device_t and calling
  methods directly.
* Don't check acpi_BatteryIsPresent() in acpi_battery.  Leave it up to
  the hardware-specific driver (i.e. cmbat) since smart batteries seem
  to not report the "battery present" flag.
* Convert mA to mW if the battery uses those units.  CM-batteries only
  used mW so this deficiency went unnoticed.
* Clean strings reported in the battery info from any control chars.
* Only dereference the unit from ioctl_arg if the full struct is present.
  Unit wouldn't have been used later if it wasn't present but this is
  cleaner.  Translate the unit if it's not ACPI_BATTERY_ALL_UNITS.
* bzero structs before returning them to usermode for future compat.

Most of this work was submitted by Hans Petter Selasky and then majorly
reworked by myself.
