Refactor initial parsing stage

- Reduced the amount of state in the RawKeyword and ParserState classes.
 - RawKeyword class has normal constructor - remove init method.
 - The Rawxxx symbols are module private and the header files are not installed.
 - Removed several unused static methods from Rawxxx and ParserKeyword.
