mod_sasl2_fast: Fix harmless off-by-one error (invalidates existing tokens!) Problem: This was causing the key to become "<token>--cur" instead of the expected "<token>-cur". As the same key was used by the code to both set and get, it still worked. Rationale for change: Although it worked, it's unintended, inconsistent and messy. It increases the chances of future bugs due to the unexpected format. Side-effects of change: Existing '--cur' entries will not be checked after this change, and therefore existing FAST clients will fail to authenticate until they attempt password auth and obtain a new FAST token. Existing '--cur' entries in storage will not be cleaned up by this commit, but this is considered a minor issue, and okay for the relatively few FAST deployments.

Introduction
============

This module implements [XEP-0288: Bidirectional Server-to-Server
Connections](http://xmpp.org/extensions/xep-0288.html). It allows
servers to use a single connection for sending stanzas to each other,
instead of two connections (one for stanzas in each direction).

Install and enable it like any other module. It has no configuration.
