Patch #1436130: codecs.lookup() now returns a CodecInfo object (a subclass

Browse source 
of tuple) that provides incremental decoders and encoders (a way to use
stateful codecs without the stream API). Functions
codecs.getincrementaldecoder() and codecs.getincrementalencoder() have
been added.

The encoding string is looked up converted to all lower-case
characters. This makes encodings looked up through this mechanism
effectively case-insensitive.

As side effect, this tries to load the encodings package, if not
yet done. This is part of the lazy load strategy for the encodings
