Summary: Incremental codecs

Initial Comment:
This patch extends the codec machinery to add
incremental codecs: stateful codecs that don't use a
stream API. It adds the following stuff: a class
codecs.CodecInfo (a subclass of tuple), that is used as
the return value of codecs.lookup();
codecs.IncrementalEncoder and codecs.IncrementalDecoder
(the basic interface classes),
codecs.BufferedIncrementalDecoder (a class that can be
used to implement decoders that must handle incomplete
input); codecs.iterencode() and codecs.iterdecode()
(generators that use the incremental codecs for
encoding/decoding an input iterable). On the C level
PyCodec_IncrementalEncoder() and
PyCodec_IncrementalDecoder() are added.

This second version of the patch enhances
codecs.iterencode() and codecs.iterdecode(), so that
additional keyword arguments are passed through to the
Incremental(De|En)coder constructor.
