DERBY-3364: Replication failover implementation must be modified to fail at the master after slave has been stopped
Contributed by V Narayanan
Changes:
M java/engine/org/apache/derby/impl/services/replication/net/ReplicationMessageTransmit.java
* Set a timeout on the socket that is translated as a timeout on the
  reads on the I/P streams 
M java/engine/org/apache/derby/impl/services/replication/master/MasterController.java
* Stop log shipment and tear down network both with successful and
  non-successful failover.
