Backport the enum package from the abortive Mailman 3 branch. This lets us

use much nicer identifiers for constants than plain ints or strings.  New code
using enumerating constants should use subclasses of enum.Enum.

Along those lines, the passwords.py module has been rewritten to use enum
constants instead of strings.  So now e.g. the default password scheme is
Mailman.passwords.Schemes.ssha and there are Scheme.pbkdf2 and Scheme.sha
(etc) schemes as well.

Also, rework the passwords.py implementation to better support unicode
passwords.  This elaborates on Tokio's r8160 by recognizing that the hash
algorithms always operate on byte-strings not on unicodes.  Thus if the secret
or response are unicodes, encode them to byte-strings via utf-8 before hashing
and comparing.

Unit tests added for both enums and passwords.
