++/**
++ * Verify that the 'from' attribute of an IQ reply is a valid match for
++ * a given IQ request. The expected behavior is outlined in section
++ * 8.1.2.1 of the XMPP CORE spec (RFC 6120). We consider the reply to
++ * be a valid match if any of the following is true:
++ * - Request 'to' matches reply 'from' (including the case where
++ * neither are set).
++ * - Request 'to' was empty and reply 'from' is server JID.
++ * - Request 'to' was empty and reply 'from' is my JID. The spec says
++ * we should only allow bare JID, but we also allow full JID for
++ * compatibility with some servers.
++ *
++ * These rules should allow valid IQ replies while preventing spoofed
++ * ones.
++ *
++ * For more discussion see the "Spoofing of iq ids and misbehaving
++ * servers" email thread from January 2014 on the jdev and security
++ * mailing lists.
++ *
++ * @return TRUE if this reply is valid for the given request.
