Added list-unsubscribe header match.

2003-11-28  Not Zed  <NotZed@Ximian.com>

        * camel-mime-utils.c (mail_list_magic[]): Added list-unsubscribe
        header match.

2003-11-26  Not Zed  <NotZed@Ximian.com>

        * camel-smime-context.c (sm_verify_cmsg): take a stream rather
        than a part for the content.
        (sm_verify): get the content directly as a stream.

        * camel-multipart-signed.c
        (camel_multipart_signed_get_content_stream): new api to get the
        content stream which will match the signed version.
