Subject: [PATCH] Properly detect the battery charging status under FreeBSD.

The hw.acpi.battery.state sysctl returns a bitmask of flags as
defined in <dev/acpica/acpiio.h>.  Use constants from this header
to examine the state and check for the charging flag to determine
if the battery is charging.
