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.
