Fixed pushing of Seti state to peer: using the OortComet instead of
the LocalSession, since the peer may not be subscribed yet (and
therefore push via LocalSession would have no subscribers,
while push via OortComet would be guaranteed to arrive).
Fixed SetiTest by using the correct number of parties in latches.
Reverted usage of try/finally, since no exceptions should escape.
Using one HttpClient per BayeuxClient to avoid that stopping a shared
HttpClient when stopping other components causes tests to fail.
Merged branch '2.7.x' into 'master'.
