util.stanza: Don't automatically generate ids for iq stanzas Users of this API should provide their own id attribute that meets their uniqueness requirements. The current implementation leaks information (i.e. how many iq stanzas have been sent by the server to other JIDs). Providing any strong guarantees of randomness here would need to pull in additional dependencies that we don't want in this simple library.
