Improve handling parameters clashing with language keywords

Browse source 
Previously, only Python tried to preserve the original parameter name
(by prepending or appending an underscore to it, but otherwise keeping
the original name) if it conflicted with one of the language keywords,
while all the other languages replaced the parameter name with a
meaningless "argN" in this case.

Now do this for all languages as this results in more readable generated
code and there doesn't seem to be any reason to restrict this to Python
only.
