Fixed problem where NULL package elements were not returned to
the AcpiEvaluateObject interface correctly. Instead of returning a
NULL ACPI_OBJECT package element, the element was simply ignored,
potentially causing a buffer overflow and/or confusing the caller
who expected a fixed number of elements.

Fixed a problem where an extraneous debug message was produced for
package objects (when debugging enabled). The message "Package
List length larger than NumElements count" is now produced in
the correct case, and is also an error message rather than a
debug message. Added a debug message for the opposite case, where
NumElements is larger than the Package List, and the package has
been padded out with NULL elements.

Fixed a problem where buffer and package objects passed as
arguments to a control method via the external AcpiEvaluateObject
interface could cause an AE_AML_INTERNAL exception depending on the
order and type of operators executed by the target control method.

Fixed a problem where a CopyObject to RegionField, BankField, and
IndexField objects did not perform an implicit conversion as it
should. These types must retain their initial type permanently as
per the ACPI specification. However, a CopyObject to all other
object types should not perform an implicit conversion, as per
the ACPI specification.

Fixed a problem where resource descriptor size optimization
could cause a problem when a _CRS resource template is passed
to a _SRS method. The _SRS resource template must use the same
descriptors (with the same size) as returned from _CRS. This
change affects the following resource descriptors: IRQ/IRQNoFlags
and StartDependendentFn/StartDependentFnNoPri.

Implemented full disassembler support for the following new ACPI
tables: BERT, EINJ, and ERST. Partial disassembler support for
the complicated HEST table. These tables support the Windows
Hardware Error Architecture (WHEA).

Fixed a regression introduced in version 20071114. The ACPI_HIDWORD
macro was inadvertently changed to return a 16-bit value instead of
a 32-bit value, truncating the upper Dword of a 64-bit value. This
macro is only used to display debug output, so no incorrect
calculations were made.

Fixed a problem with the SizeOf operator when used with Package
and Buffer objects. These objects have deferred execution for some
arguments, and the execution is now completed before the SizeOf is
executed. This problem caused unexpected AE_PACKAGE_LIMIT errors
on some systems.
