Summary: codecs.StreamRecoder.next doesn't encode

Initial Comment:
Codecs.StreamRecode.next does't encode the data it 
gets from self.reader.next. This breaks the "for line in 
codecs.EncodedFile(...)" idiom.

Checked in as:
Lib/codecs.py 1.48/1.35.2.10

I'll try to add tests for StreamRecoder tomorrow.

StreamRecoder is broken in its current form, as it uses the
stateless codec for the frontend encoding. Recoding from
e.g. latin-1 to utf-16 will return a BOM for every call to
read() which is clearly wrong. What gets read from the
backend stream should be pushed through a *stateful*
encoder. BTW, a feed style API would help here ;)
