Util.objectFromByteBuffer() is inefficient
------------------------------------------

                 Key: JGRP-268
                 URL: http://jira.jboss.com/jira/browse/JGRP-268
             Project: JGroups
          Issue Type: Task
    Affects Versions: 2.3 SP1, 2.3, 2.2.9 SP3 (2.2.9.3), 2.2.9.2
            Reporter: Bela Ban
         Assigned To: Bela Ban
            Priority: Minor
             Fix For: 2.4


The implementation tries to unmarshal as an Externalizable/Serializable, when an exception is thrown, we try for Streamable. This is inefficient when we send a lot of Streamable types, because we always run into the exception.
Fix: add an additional byte in objectToByteBuffer() which marks the object as Streamable or Externalizable/Serializable.
