        Walk every member and call a function on the keyword and value.

        Return a dictionary of the return values

        If the function raises an exception, raise the errror
        unless ``raise_errors=False``, in which case set the return value to
        ``False``.

        Any unrecognised keyword arguments you pass to walk, will be pased on
        to the function you pass in.

        Note: if ``call_on_sections`` is ``True`` then - on encountering a
        subsection, *first* the function is called for the *whole* subsection,
        and then recurses into it's members. This means your function must be
        able to handle strings, dictionaries and lists. This allows you
        to change the key of subsections as well as for ordinary members. The
        return value when called on the whole subsection has to be discarded.

        See  the encode and decode methods for examples, including functions.

        .. caution::

            You can use ``walk`` to transform the names of members of a section
            but you mustn't add or delete members.

        Test the ConfigObj against a configspec.

        It uses the ``validator`` object from *validate.py*.

        To run ``validate`` on the current ConfigObj, call: ::

            test = config.validate(validator)

        (Normally having previously passed in the configspec when the ConfigObj
        was created - you can dynamically assign a dictionary of checks to the
        ``configspec`` attribute of a section though).

        It returns ``True`` if everything passes, or a dictionary of
        pass/fails (True/False). If every member of a subsection passes, it
        will just have the value ``True``. (It also returns ``False`` if all
        members fail).

        In addition, it converts the values from strings to their native
        types if their checks pass (and ``stringify`` is set).

        If ``preserve_errors`` is ``True`` (``False`` is default) then instead
        of a marking a fail with a ``False``, it will preserve the actual
        exception object. This can contain info about the reason for failure.
        For example the ``VdtValueTooSmallError`` indeicates that the value
        supplied was too small. If a value (or section) is missing it will
        still be marked as ``False``.

        You must have the validate module to use ``preserve_errors=True``.

        You can then use the ``flatten_errors`` function to turn your nested
        results dictionary into a flattened list of failures - useful for
        displaying meaningful error messages.

    An example function that will turn a nested dictionary of results
    (as returned by ``ConfigObj.validate``) into a flat list.

    ``cfg`` is the ConfigObj instance being checked, ``res`` is the results
    dictionary returned by ``validate``.

    (This is a recursive function, so you shouldn't use the ``levels`` or
    ``results`` arguments - they are used by the function.

    Returns a list of keys that failed. Each member of the list is a tuple :
    ::

        ([list of sections...], key, result)

    If ``validate`` was called with ``preserve_errors=False`` (the default)
    then ``result`` will always be ``False``.

    *list of sections* is a flattened list of sections that the key was found
    in.

    If the section was missing then key will be ``None``.

    If the value (or section) was missing then ``result`` will be ``False``.

    If ``validate`` was called with ``preserve_errors=True`` and a value
    was present, but failed the check, then ``result`` will be the exception
    object returned. You can use this as a string that describes the failure.

    For example *The value "3" is of the wrong type*.
