[issue31829] Portability issues with pickle

[Serhiy Storchaka]

This can help with migrating to Python 3.

Python 2 programs often open files in text (default) mode for pickling and unpickling. With these changes you will get a warning when run the interpreter with the -3 option. You can also make the producer opening a file in binary mode for compatibility with Python 3, and be sure that the Python 2 consumer will read it correctly even from a file opened in text mode on Windows.
