[issue16820] configparser.ConfigParser.clean and .update bugs

[Wolfgang Scherer]

New submission from Wolfgang Scherer:

configparser.ConfigParser.clean() always fails:

    >>> cfg = configparser.ConfigParser()
    >>> if not hasattr(configparser.ConfigParser, 'clear'):
    ...     configparser.ConfigParser.clear = configparser_clear_compat
    >>> cfg.clear() #doctest: +ELLIPSIS
    Traceback (most recent call last):
    ...
    ValueError: Cannot remove the default section.

configparser.ConfigParser.update() overwrites all sections except DEFAULT instead of updating them.
