[JDEV] Invisibility and transports

[Thomas Muldowney]

I'm remembering old conversations about this now, and the problem was
that everything is just a JID and distinguishing tranports is a non
trivial task (because they could be remote).  So it's best to just go
offline/invis and let the clients deal with it if they want to. 
Although that really strains the transports oddly since they kill the
session and then immediately bring it back up.  Maybe if the client sent
the invisible to the transports first and the jabberd tracked jids that
had been notified already so it wouldn't send the offlines to them. 
Then the transports can take the correct action without stopping and
starting a remote session a lot.
