NFInst builtin function handling.

   - Most builtin functions are now handled.
   - A new builtin file NFFrontEnd/NFModelicaBuiltin.mo
     is used by the new instantiation now.
   - Builtin functions are handled by a combination of
      - gnenric functions
      - overloading
      - and special intenral handling when needed.

   - Error messages need to be improved in a number of places.
   - There are some builting functions which will pass
     when not suppsoed to. The will be fixed.
