- X-Sympa-*: header fields are stripped at first of message parsing.  They will no longer included into outgoing messages.
- Conversely, new Message::to_string() adds header fields above at the top of serialized messages.
- Message::new() now takes string and metadata as argument: MIME::Entity instance, "message_in_spool" hashref and filename are omitted.
- Tentative Message::new_from_file() is a wrapper of above.  It may be removed when refactoring will completed.
- New tools::unmarshal_metadata() to explode metadata from file name of spooled message.  This uses new tools::split_listname() utility function to analyze list identifiers.
- sympa ::DoFile() was renamed to process_message() and takes Message as argument.
- Message::check_param_status() and Message::check_dkim_signature() are separated from Message::new(), because they are needed by incoming messages (in "msg" queue).  ToDo: decrypt() and check_smime_Signature() should be also handled in the same way.
- mail::mail_file() changed its prototype.  ToDo: this would be splitted into Message::new_from_template() and mail::sending().
