[Python-3000] Two new test failures (one OSX PPC only)

[Guido van Rossum]

I see two new tests failing tonight:

- test_xmlrpc fails on all platforms I have. This is due to several
new tests that were merged in from the trunk; presumably those tests
need changes due to str vs. bytes.

- test_codecs fails on OSX PPC only. This is in the new UTF-32 codecs;
probably a byte order issue.

There's still one leak that Neal would like to see fixed, in
test_zipimport. Instructions to reproduce: in a *debug* build, run
this command:

  ./python Lib/test/regrtest.py -R1:1: test_zipimport

This reports 29 leaked references.
