Allow generic data types in custom acpi tables. Field names are now optional. Any line can be split to multiple lines using continuation char (\). Large buffers now use line-continuation char and no colon on the continuation lines. See grammar update in the iASL compiler reference. ACPI BZ 910,911. Lin Ming, Bob Moore.
