Flavio Junqueira updated ZOOKEEPER-1082:
----------------------------------------

    Attachment: ZOOKEEPER-1082.patch

New version of the patch. I have cleaned up a bit and added an explicit 
FLEBackwardCompatibilityTest class. It is essentially a copy of 
FLELostMessageTest, but with a hardcoded messages that look like the current 
notifications in the trunk code.  

Also note that there are no modifications to LeaderElection, so LETest passing 
indicates that it is backward compatible with respect to that implementation of 
leader election.

> modify leader election to correctly take into account current epoch
