Helper function to format and quote a single header parameter using the
strategy defined in RFC 2231.
Particularly useful for header parameters which might contain
non-ASCII values, like file names. This follows
`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 ``bytes`` or `str``.
:ret:
An RFC-2231-formatted unicode string.

Helper function to format and quote a single header parameter using the
HTML5 strategy.
Particularly useful for header parameters which might contain
non-ASCII values, like file names. This follows the `HTML5 Working Draft
Section 4.10.22.7`_ and matches the behavior of curl and modern browsers.

:param name:
The name of the parameter, a string expected to be ASCII only.
:param value:
The value of the parameter, provided as ``bytes`` or `str``.

RequestFielda
A data container for request body parameters.
:param name:
The name of this request field. Must be unicode.
:param data:
The data/value body.
:param filename:
An optional filename of the request field. Must be unicode.
:param headers:
An optional dict-like object of headers to initially use for the field.
:param header_formatter:
An optional callable that is used to encode and format the headers. By
default, this is :func:`format_header_param_html5`.

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.

Overridable helper function to format a single header parameter. By
default, this calls ``self.header_formatter``.
: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.

'Content-Disposition' fields.
:param header_parts:
A sequence of (k, v) tuples or a :class:`dict` of (k, v) to format
as `k1="v1"; k2="v2"; ...`.
