    Helper function to format and quote a single header parameter.

    Particularly useful for header parameters which might contain
    non-ASCII values, like file names. This follows RFC 2231, as
    suggested by RFC 2388 Section 4.4.

    :param name:
        The name of the parameter, a string expected to be ASCII only.
    :param value:
        The value of the parameter, provided as a unicode string.

        A :class:`~urllib3.fields.RequestField` factory from old-style tuple parameters.

        Supports constructing :class:`~urllib3.fields.RequestField` from
        parameter of key/value strings AND key/filetuple. A filetuple is a
        (filename, data, MIME type) tuple where the MIME type is optional.
        For example::

            'foo': 'bar',
            'fakefile': ('foofile.txt', 'contents of foofile'),
            'realfile': ('barfile.txt', open('realfile').read()),
            'typedfile': ('bazfile.bin', open('bazfile').read(), 'image/jpeg'),
            'nonamefile': 'contents of nonamefile field',

        Field names and filenames must be unicode.

        Helper function to format and quote a single header.

        Useful for single headers that are composed of multiple items. E.g.,
        'Content-Disposition' fields.

            A sequence of (k, v) typles or a :class:`dict` of (k, v) to format

        Makes this request field into a multipart request field.

        This method overrides "Content-Disposition", "Content-Type" and
        "Content-Location" headers to the request parameter.

        :param content_type:
            The 'Content-Type' of the request body.
        :param content_location:
            The 'Content-Location' of the request body.
