Claudiu Popa 50365affc1 Normalize the payload to bytes before delegating to userdatautils
userdatautils is expected to operate on bytes, but on Python 3,
email.message.Message.get_payload returns a string, not a byte string
as for Python 2. This patch also includes a change to parthandler.py,
where we're using encoding.write_file instead of writing the file manually,
since encoding.write_file knows how to normalize its arguments properly.
