        * camel-cipher-context.h: Added a protocol field for users to use.

        * camel-stream-filter.c (do_read): Sigh, the pre-size is READ_PAD
        not READ_SIZE.  Big difference.
        (READ_PAD): Bumped upto 128 from 64, so we can fit a typical line
        in full.

        * providers/imap/camel-imap-folder.c (get_content): Changed to
        load multipart/signed as an opaque block into the right kind of
        object.

        * camel-multipart.h (struct _CamelMultipart): Removed the boundary
        field.  It wans't actually used anywhere.

        * camel-seekable-substream.c
        (camel_seekable_substream_new_with_seekable_stream_and_bounds):
        Shortened this stupidly long name to just :new(), its the only way
        its ever used.  Fixed all callers.

        * camel-multipart-signed.[ch]: new wrapper for multipart/signed
        types.  We need to treat the entire content as a blob of data for
        transport purposes.  This also cleans up a lot of the sign/verify
        handling.

        * camel-mime-part-utils.c
        (camel_mime_part_construct_content_from_parser): Just call
        camel_multipart_construct_from_parser for multipart parts, also
        use a multipart_signed for multipart/signed types.

        * camel-multipart.c (camel_multipart_construct_from_parser): New
        virtual function for multiparts to buld themselves.
        (construct_from_parser): Implement for normal multiparts.
        (toplevel): Got rid of a warning, it'll never be an abstract
        class.

        * camel-pgp-context.c (pgp_hash_to_id):
        (pgp_id_to_hash): Implement.
        (camel_pgp_context_init): Init the pgp protocol specifier.

        * camel-cipher-context.c (camel_cipher_id_to_hash):
        (camel_cipher_hash_to_id): Util virtual methods to handle the
        cipher id string.

        * camel-mime-filter-canon.[ch]: A new filter, end/start of line
        canonicalisation filter.  Can escape "From " and strip trailing
        whitespace, and canonicalise the end of line to crlf or to lf.

        * camel-multipart.h (struct _CamelMultipart): Removed the
        'parent', nothing used it, anywhere.  Cleaned up some formatting
        slightly.
