Add the -i flag to acpiconf(8) to retrieve battery information.
Rename a few structure elements.

Add a system notify handler in addition to the device notify handler.
At least some Toshiba notebooks use a Notify of 0 or 1 for this.

De-inline functions which do not need to be inline. Move the DEVMETHOD
block to where it is in similar drivers.

Style cleanups to match the rest of this directory. For acpi_battery.c,
remove unused includes.

Allow non-privilaged user to retrive battery or AC line information.

This is a workaround for embedded controller operations which is
unstable for about a minute (typically 30 or 40 sec.) at boot time.

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.

When ensuring the destination buffer is truncated for a string obtained
