Hi.

I have committed and implementation of the JBIG2 decoder filter.

During the development of this filter I found a problem in the streams
code and fixed it: now the semantics of finish_p also apply for
reading filters. The consequence is that the encoding filters now also
work in reading streams.

No modifications are required in the existing filters. The semantics
explained in
http://www.gnupdf.org/Lib:Architecture/Base_Layer/Stream_Module#Filter_implementations
have not changed.
