  Refactored glslang grammar files to make:
  - lexer and parser reentrant
  - line number handling automatic
  
  Caveats:
  - The preprocessor is still not thread-safe and full of bugs. I have another not-yet-ready patch to replace the preprocessor.
  - The grammar files use options that are not supported by the old versions of flex and bison checked into compiler/tools. So I need to check-in the generated lexer-parser along with a shell script to generate them.
