* camel-mime-part-utils.c
(simple_data_wrapper_construct_from_parser): canonicalise the
charset name (if it is an iso charset) so that our strncasecmp to
see if it is an iso-8859-# charset will be guarenteed to work on
all systems.
(canon_charset_name): New function to return the canonical iso
charset name.
(simple_data_wrapper_construct_from_parser): If the charset is
NULL *or* the charset == "us-ascii" then check that it is 7bit
clean to decide if it is rawtext (we did not check the case where
charset was "us-ascii" before).
