this routine replaces the _read_part routine and does not store the part
2000-02-15 bertrand <bertrand@helixcode.com> * camel/camel-multipart.c (_localize_part): this routine replaces the _read_part routine and does not store the part in a buffer. (_set_input_stream): use the set_input_stream instead of the construct_from_stream. each bodypart is given an input stream. * camel/camel-mime-part-utils.c: include the data-wrapper-repository header. (camel_mime_part_construct_content_from_stream): use the set_input_stream instead of the construct_from_stream method. * camel/camel-seekable-substream.c (_set_bounds): cur position is set to 0 not to inf_bound.
