[ACPI] ACPICA 20041015 from Bob Moore

Signed-off-by: Len Brown <len.brown@intel.com>

Note: ACPI CA is currently undergoing an in-depth and
complete formal evaluation to test/verify the following
areas. Other suggestions are welcome. This will result in
an increase in the frequency of releases and the number
of bug fixes in the next few months.

- Functional tests for all ASL/AML operators
- All implicit/explicit type conversions
- Bit fields and operation regions
- 64-bit math support and 32-bit-only "truncated" math support
- Exceptional conditions, both compiler and interpreter
- Dynamic object deletion and memory leaks
- ACPI 3.0 support when implemented
- External interfaces to the ACPI subsystem

Fixed two alignment issues on 64-bit platforms -
within debug statements in acpi_ev_gpe_detect and
acpi_ev_create_gpe_block. Removed references to the
Address field within the non-aligned ACPI generic address
structure.

Fixed a problem in the Increment and Decrement operators
where incorrect operand resolution could result in the
inadvertent modification of the original integer when the
integer is passed into another method as an argument and
the arg is then incremented/decremented.

Fixed a problem in the FromBCD operator where the upper
32-bits of a 64-bit BCD number were truncated during
conversion.

Fixed a problem in the ToDecimal operator where the length
of the resulting string could be set incorrectly too long
if the input operand was a Buffer object.

Fixed a problem in the Logical operators (LLess,
etc.) where a NULL byte (0) within a buffer would
prematurely terminate a compare between buffer objects.

Added a check for string overflow (>200 characters as per
the ACPI specification) during the Concatenate operator
with two string operands.
