Reduce size of large headers: place data into message itself
------------------------------------------------------------

                 Key: JGRP-1259
                 URL: https://jira.jboss.org/browse/JGRP-1259
             Project: JGroups
          Issue Type: Feature Request
            Reporter: Bela Ban
            Assignee: Bela Ban
             Fix For: 2.12


When we send a view around, we essentially create an empty Message and attach a GmsHeader.VIEW with the new view.
If the view consists of 200 members, the view header will be very big and the message is still empty (null buffer).

The issue here is that FRAG2 only fragments the message's buffer (this is faster), and so a huge header might add so much to the size of a serialized message that the transport (UDP) won't be able to send it !

SOLUTION: still use the header (e.g. GmsHeader.VIEW), but place potentially large payloads into the message. This will allow FRAG2 to fragment the message very efficiently.
