[Python-3000] Need help enforcing strict str/bytes distinctions

[Guido van Rossum]

As anyone following the py3k checkins should have figured out by now,
I'm on a mission to require all code to be consistent about bytes vs.
str. For example binary files will soon refuse str arguments to
write(), and vice versa.

I have a patch that turns on this enforcement, but I have anout 14
failing unit tests that require a lot of attention. I'm hoping a few
folks might have time to help out.

Here are the unit tests that still need work:

test_asynchat
test_bsddb3
test_cgi
test_cmd_line
test_csv
test_doctest
test_gettext
test_httplib
test_shelve
test_sqlite
test_tarfile
test_urllib
test_urllib2
test_urllib2_localnet

Attached is the patch that makes them fail. Note that it forces an
error when you use PyBUF_CHARACTERS when calling PyObject_GetBuffer on
a str (PyUnicode) object.
