Improve the contrib/slapd-modules/passwd/totp module in the following ways:
- Add support for two-factor (password+OTP) authentication, where password can be defined via any currently-supported scheme. - Allow the OTP from the previous time window to be accepted, provided there has been no successful bind in or after that time window. This avoids false authentication failures if for example the time window rolls over as the OTP is being entered or transmitted.
