[ACPI] ACPICA 20060210

Removed a couple of extraneous ACPI_ERROR messages that
appeared during normal execution. These became apparent
after the conversion from ACPI_DEBUG_PRINT.

Fixed a problem where the CreateField operator could hang
if the BitIndex or NumBits parameter referred to a named
object. From Valery Podrezov.

Fixed a problem where a DeRefOf operation on a buffer
object incorrectly failed with an exception. This also
fixes a couple of related RefOf and DeRefOf issues.
From Valery Podrezov.

Fixed a problem where the AE_BUFFER_LIMIT exception was
returned instead of AE_STRING_LIMIT on an out-of-bounds
Index() operation. From Valery Podrezov.

Implemented a memory cleanup at the end of the execution
of each iteration of an AML While() loop, preventing the
accumulation of outstanding objects. From Valery Podrezov.

Eliminated a chunk of duplicate code in the object
resolution code. From Valery Podrezov.

Fixed several warnings during the 64-bit code generation.
