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.

Add support for [XEP-0386: Bind 2], which is a new method for clients to bind
resources and establish sessions in XMPP, using SASL2. **Note: At the time of
writing (November 2022), this plugin implements a version of XEP-0386 that is
still working its way through the XSF standards process. See [PR #1217](https://github.com/xsf/xeps/pull/1217)
for more information and current status.**

This module depends on [mod_sasl2]. It exposes no configuration options.
