Detect sign extension problems when variable is a reference (#3637)

Reijo Tomperi 194327048a Add InternalError and change MathLib to throw it in case of an error.
- Previously MathLib errors did not provide a filename, but after this change at least source file name should be printed
and if token is provided, also line number should be printed.
- Change also Token to use InternalError
- Modify Cppcheck-class to catch InternalError instead of Token
- Run dmake to update Makefile
