[ACPI] ACPICA 20050916

Fixed a problem within the Resource Manager where
support for the Generic Register descriptor was not fully
implemented.  This descriptor is now fully recognized,
parsed, disassembled, and displayed.

Restructured the Resource Manager code to utilize
table-driven dispatch and lookup, eliminating many of the
large switch() statements.  This reduces overall subsystem
code size and code complexity.  Affects the resource parsing
and construction, disassembly, and debug dump output.

Cleaned up and restructured the debug dump output for all
resource descriptors.  Improved readability of the output
and reduced code size.

Fixed a problem where changes to internal data structures
caused the optional ACPI_MUTEX_DEBUG code to fail
compilation if specified.
