Consolidate state transfer API to use streams
---------------------------------------------

                 Key: JGRP-563
                 URL: http://jira.jboss.com/jira/browse/JGRP-563
             Project: JGroups
          Issue Type: Task
            Reporter: Vladimir Blagojevic
         Assigned To: Vladimir Blagojevic
             Fix For: 3.0

Although streaming state transfer has its advantages over byte based state transfer, byte based state transfer is absolutely necessary since streaming based transfer relies on plain sockets that are not firewall friendly. However, that does not mean that we cannot consolidate state transfer API at application level and mask byte based transfer with streams. We have already done this in JBC 2.0 so there is no reason not to do it on JGroups level as well.

Advantages:
- simpler state transfer API
- interchangeable state transfer mechanism without affect on application
- simplification of client application

Disadvantages:
- we break current API by eliminating getState(byte[]) and setState(byte [])
