Summary: zlib/bz2_codec doesn't support incremental decoding

Initial Comment:
http://svn.python.org/view/python/trunk/Lib/encodings/zlib_codec.py?rev=43045&view=auto

Incremental encoding/decoding must be stateful.
Please use compressobj/decompressobj object.

Incremental(Encoder|Decoder)/Stream(Reader|Writer)
don't work with current code at all.

Fixed the incremental coders/decoders in rev. 52529, 52530
(2.5).

The StreamReaders/Writers can't be fixed as easily, because
their encode/decode methods don't have a "final" flag, so
they wouldn't know when to flush the compress object.
