+	Introduction of the notion of filter_t object takes a stream and
+	perform some filtering on it.  All the decoding streams will move
+	to this i.e. quoted-printable, base64 etc .. This scheme will also
+	permit users to add to the list new filters.  Still work in progress.
+
+	* mailbox/Makefile.am : Add filter.c filter_rfc822.c.

+	a temporary file, the stream was not "own" by the body_t.
