[PATCH 3/3] Fix references to self.warning()

[Philipp Hahn <hahn@xxxxxxxxxxxxx>]

Only the class CParser declares a method warning(), but the other
classes still try to call their self.warning() method, which fails.

Move the warning() functions to its own base classe and inherit from
that in all other classes.
