In particular, parse comma-separated lists where the elements of
the list may include quoted-strings.  A quoted-string could
contain a comma.  A non-quoted string could have quotes in the
middle.  Quotes are removed automatically after parsing.

It basically works like :func:`parse_set_header` just that items
may appear multiple times and case sensitivity is preserved.

The return value is a standard :class:`list`:

>>> parse_list_header('token, "quoted value"')
['token', 'quoted value']

To create a header from the :class:`list` again, use the
:func:`dump_header` function.

:param value: a string with a list header.
