Updated copyright. Deleted erroneous "Module Name" line. Changed preceding macro, enum, and structure comments to Doxygen style. Changed existing structure member comments to Doxygen style. Cleaned up some comment blocks to conform to the coding specification. Changed @bug comments on structure members to the postfix style so that the correct members are documented. Removed duplicate, orphan, EFI_TO_COMPATIBILITY16_BOOT_TABLE comment and move remaining comment to the correct location. Add descriptive comment to terminating #endif.
