[issue12536] lib2to3 BaseFix class creates un-needed loggers leading to refleaks

[Éric Araujo]

If the logger attribute is part of the official API and Benjamin doesn’t think it wise to just remove it, I think we should either start deprecating it (using a property), or set it to a shared logger object instead of creating one per file.
