Create a new CamelMultipartSigned object.
A MultipartSigned should be used to store and create parts of type "multipart/signed". This is because multipart/signed is entirely broken-by-design (tm) and uses completely different semantics to other mutlipart types. It must be treated as opaque data by any transport. See rfc 3156 for details.
There are 3 ways to create the part: Use construct_from_stream. If this is used, then you must set the mime_type appropriately to match the data uses, so that the multiple parts my be extracted.
Use construct_from_parser. The parser MUST be in the CAMEL_MIME_PARSER_STATE_HEADER state, and the current content_type MUST be "multipart/signed" with the appropriate boundary and it SHOULD include the appropriate protocol and hash specifiers.
Use sign_part. A signature part will automatically be created and the whole part may be written using write_to_stream to create a 'transport-safe' version (as safe as can be expected with such a broken specification).
Returns : |

CamelStream * camel_multipart_signed_get_content_stream (CamelMultipartSigned *mps, CamelException *ex);
Get the raw signed content stream of the multipart/signed MIME part suitable for use with verification of the signature.
