Apply diff2.txt from SF patch http://www.python.org/sf/566999 

This patch enhances Python/import.c/find_module() so
that unicode objects found in sys.path will be treated
as legal directory names (The current code ignores
anything that is not a str). The unicode name is
converted to str using Py_FileSystemDefaultEncoding.

Core and builtins
- Unicode objects in sys.path are no longer ignored but treated
as directory names.
- The built-ins slice() and buffer() are now callable types. The
types classobj (formerly class), code, function, instance, and
