Review request for hbase and Jonathan Gray.


Summary
-------

Here is patch I've been testing with up on cluster.  Adds debugging and two fixes -- one setting
state to OPEN on receipt of a rs opened event and two, resetting a watcher getting data over
in zkutil (as per its documentation claims).


This addresses bug hbase-3159.
