mod_smacks: Improve activation of smacks on outgoing s2s
Using a timer was a hack to get around that stream features are not
available at the right time and sendq stanzas were stored as strings
so could not be counted properly. The later has now been fixed and the
former is fixed by recording the relevant stream feature on the session
so that the correct version of XEP-0198 can be activated once the
connection has been authenticated and is ready to start.
