Python 3 preparation: use bytes more in password handling. This patch adds enough fixes to use bytes to work for PBKDF2 passwords, but probably not for the other hash algorithms supported. It would make sense for the PBKDF2 code to use the Python hashlib support for PBKDF2 as the first choice before M2Crypto and the local PBKDF2 implementation (hashlib supports it in 2.7.8, 3.4 and later), but it still seems appropriate to fix the local code to handle bytes properly anyway.
