d4085a3ffe ACPICA: Predefined name repair: automatically remove null package elements
This change will automatically remove embedded and trailing NULL
package elements from returned package objects that are defined
to containe a variable number of sub-packages. The driver is then
presented with a package with no null elements to deal with.

e3fe0913b8 ACPICA: Fix memory leak for ill-formed Package objects
Fixes a possible memory leak in the interpreter for package
objects if the package initializer list is longer than the
defined size of the package. This apparently can only happen
if the BIOS changes the package size on the fly (seen in a _PSS
object), as both iASL and the other compiler do not allow this.
The interpreter will truncate the package to the defined size
(and issue an error message), but can leave the extra objects
undeleted if they have been pre-created during the argument
processing (such is the case if the package consists of a number
of sub-packages as in the _PSS.) ACPICA BZ 805.

53e9387bdd ACPICA: ACPI 4.0 : Add new return package type, restructure module.
Added one new package type, a package that contains a revision number and
a variable number of sub-packages. Restructured the module to
put the sub-package list traversal in a separate function.

e5f69d6ef7 ACPICA: Add repair for predefined methods that return nested packages
Fixes a problem where a predefined method is defined to return
a variable-length Package of sub-packages. If the length is one,
the BIOS code occasionally creates a simple single package with
no sub-packages. This code attempts to fix the problem by wrapping
a new package object around the existing package. ACPICA BZ 790.
