Message 208969 - Python tracker

Ok, here's a new patch.  This one fixes the issues I found in my last patch (HKEY return converter in winreg, mess from previous return converter attempts in msvcrt), and switches all four modules to a two-pass output scheme.  This should be basically what I want to commit, once 20189 is committed.

If you'd like a non-two-pass patch for review, let me know.
