Add the CamelMimePartEncodingType definition here.
2003-07-14 Jeffrey Stedfast <fejj@ximian.com>
* camel-mime-utils.h: Add the CamelMimePartEncodingType definition
here.
* camel-mime-part.h: Remove the CamelMimePartEncodingType
definition.
* camel-mime-part-utils.c
(simple_data_wrapper_construct_from_parser): Don't do any of the
auto-detection we used to do here anymore. Just read the content
into a memory buffer and record the encoding type.
(camel_mime_part_construct_content_from_parser): Don't mangle the
Content-Type struct here anymore.
* camel-data-wrapper.c (camel_data_wrapper_init): Init encoding to
DEFAULT.
(write_to_stream): If the stream needs to be decoded, decode it.
