NakAckHeader: remove 'sender' field ?
-------------------------------------

                 Key: JGRP-1150
                 URL: https://jira.jboss.org/jira/browse/JGRP-1150
             Project: JGroups
          Issue Type: Task
            Reporter: Bela Ban
            Assignee: Bela Ban
             Fix For: 2.10


The 'sender' field is only used for retransmissions, but do we ever use it to request a retransmission on behalf of someone else ? If not, we could use msg.getSrc() instead !
Currently, an address (UUID) uses 18 bytes, so we would save 18 bytes per multicast message ! This is good as long as we don't have canonicalization of addresses yet
