Fix test_aepack and test_applesingle.

Kill some dead (commented-out) code.

test_shelve still fails thanks to bsddb not having been fixed.

Silence two innocuous warnings (_File and _collections).

division.  The other curses demos all work fine, so I'm more confident
that the curses library actually works. (Don't try to display
non-ASCII characters, of course.)

Can't guarantee I caught every spot.

I have no illusion that this fixes all issues with this module.

(To run these, you need to pass -uurlfetch to regrtest.py or runtests.sh.)

1. Removed "returns_unicode" attribute, associated code
   in the module to support that attribute, and all tests
   associated with it.
2. Parsed data is now returned as unicode strings.
3. Changed input tests to use io.BytesIO instead
   of StringIO, to reflect the byte processing
   nature of expat.

I made Carbon.File.pathname return unicode, by analogy with
macpath.abspath. There could easily be other bugs of the same sort in this
file. The uses of PyString_FromString*() in particular look sketchy.

(This doesn't fix test_cookielib, just removes the SyntaxError.)

problems on my OSX laptop.  use a condition variable instead.

This makes test_resource.py pass, and I think it's the right thing
to do: if you're closing a file after encountering an I/O error
there's nothing you can do about it.  If you want the error, you
can call flush() yourself.

its failure means much, now that the handling of unicode and bytes has
changed so much.

I *think* it's okay no longer to require that compiling a Unicode
string with a coding declaration fails; it seems appropriate to
just ignore it.

Unfortunately this breaks datetime pickling.  I'll have to investigate
further; reverting Martin's changes doesn't seem to help.
