Bob Moore 091f4d7186 ACPICA: Predefined name repair: fix NULL package elements
For the predefined methods that return fixed-length packages
(or subpackages), attempt repair for a NULL element. Create an
Integer of value 0, a NULL String, or a zero-length buffer as
appropriate.

Added several new options for the gcc-4 generation, and updated
the source accordingly. This includes some code restructuring to
eliminate unreachable code, elimination of some gotos, elimination
of unused return values, and some additional casting.

Bob Moore 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.

Bob Moore 465da9eb75 ACPICA: Conditionally perform complex per-predefined-name repairs
Only attempt the "complex" repairs (package sorting, buffer
expansion) if the previous "generic" validation and repair was
successful.

Bob Moore 3a58176e4f ACPICA: Remove messages if predefined repair(s) are successful
Repair mechanism was considered too wordy. Now, messages are only
unconditionally emitted if the return object cannot be repaired.
Existing messages for successful repairs were converted to
ACPI_DEBUG_PRINT messages for now. ACPICA BZ 827.

Bob Moore 34c39c7553 ACPICA: Add repair for bad _FDE/_GTM buffers
The expected return value for both names is a Buffer of 5 DWORDS.
This repair fixes two possible problems (both seen in the field):
A package of integers is returned, or a buffer of BYTEs is returned.

Bob Moore 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.

This fixes a problem where the code that attempts to repair/convert
an object of incorrect type is only executed on the first time the
predefined method is called. The mechanism that disables warnings
on subsequent calls was interfering with the repair mechanism.
