mod_invites_register_api: Use set_password() for password resets Previously the code relied on the (weird) behaviour of create_user(), which would update the password for a user account if it already existed. This has several issues, and we plan to deprecate this behaviour of create_user(). The larger issue is that this route does not trigger the user-password-changed event, which can be a security problem. For example, it did not disconnect existing user sessions (this occurs in mod_c2s in response to the event). Switching to set_password() is the right thing to do

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

[SIFT][XEP-0273] is a technology to allow clients to filter incoming
traffic on the server. This helps save bandwidth, etc.

Compatibility

Quirks
======

This implementation is a work in progress.

-   Stanzas to full JIDs get sifted correctly
-   Stanzas to bare JIDs are currently allowed/disallowed for all
    resources as a whole, and not for individual resources
-   Presence is only sent to available resources, and probes are not
    sent for unavailable reasources
-   This module currently does not interact with offline messages
    (filtered messages are dropped with an error reply)
-   Not tested with privacy lists
