Summary: restrict codec lookup to encodings package

Initial Comment:
Here's a fix for the problem recently mentioned on
python-dev, where encoding names are looked up
everywhere instead of just in the encodings package.

It was slightly more work than I anticipated because
there was a unit test that depended on the broken
behavior.  I've fixed the unittest with a hack that
temporarily extends the encodings package's __path__
with sys.path, so that the test package will appear as
a subpackage of the encodings package.  That's not very
clean; an alternative would be to patch sys.modules
(but then less of the codec import machinery is
exercised by the unit test) or to move the test codec
to the encodings package (but that places some test
code in a production package).  What would you prefer?
