Use DEVMETHOD_END macro defined in sys/bus.h instead of {0, 0} sentinel on device_method_t arrays

Centralize declaration of the debug.acpi sysctl node.

Mark all SYSCTL_NODEs static that have no corresponding SYSCTL_DECLs.

The SYSCTL_NODE macro defines a list that stores all child-elements of
that node. If there's no SYSCTL_DECL macro anywhere else, there's no
reason why it shouldn't be static.

small cleanup of acpi battery status setting and checking

This is based on the patch submitted by Yuri Skripachov.
Overview of the changes:
- clarify double-use of some ACPI_BATT_STAT_* definitions
- clean up undefined/extended status bits returned by _BST
- warn about charging+discharging bits being set at the same time

Merge ACPICA 20100121.

Import ACPICA 20090521.

Quick change to r186026. One of the conditionals was:

if (batt_sleep_ms)
AcpiOsSleep(1);

where the rest are all:

if (batt_sleep_ms)
AcpiOsSleep(batt_sleep_ms);

I can't recall why that one was different, so change it
to match the rest.

Add the sysctl debug.acpi.batt.batt_sleep_ms.

On some laptops with smart batteries, enabling battery monitoring
software causes keystrokes from atkbd to be lost. This has also been
reported on Linux, and is apparently due to the keyboard and I2C line
for the battery being routed through the same chip. Whether that's
accurate or not, adding extra sleeps to the status checking code
causes the problem to go away.

I've been running this for nearly six months now on my laptop,
it works like a charm.

* fix bst.status. We mark some bits, but forgot to reset all of them
before. The symptom is that the battery inform us its charge and discharge
at the same time...

* fix bst.rate to correctly output the (dis)charging rate. We'll use
the current average over one minute command and not the at_rate command.
Note that this method is not correct if the capacity_mode is set, but
since we don't set it ourself, it is not a problem.

The at_rate do not give the actual rate but is used to compute the
estimated time for (dis)charging a battery. We should actually
write an estimation of the actual rate using at_rate cmd and then
perform a read to the various estimators.

Import ACPI smart battery support. Newer systems (Acer, mostly) do not
support the CM-battery interface. Smart batteries can eventually be
supported without ACPI via a separate SMBus interface. The ACPI interface
uses the embedded controller for reading/writing to the SMBus, and normal
ASL definitions for locating the battery controller (since SMBus can't be
enumerated.) Also import definitions for the smart battery interface.
