Update Python 3 compatibility
* mandos (gnutls.ClientSession.__init__): Use byte string argument to
check_version() instead of a
unicode string.
(gnutls): - '' -
(ClientHandler.handle): Change default values for "fpr" and "key_id"
to be byte strings instead of unicode
strings.
(main): Use "key in dict" instead of "dict.has_key(key)".
* mandos-ctl: Fix Emacs test runner to use "--check" instead of
"--test".
(rfc3339_duration_to_delta): Change doctest string to not depend on
exact repr() string representation of
values and instead do value
comparisons.
(parse_pre_1_6_1_interval): - '' -
