Galen Shipman 5271948ec0 --- opal object changes
add object size to opal class
no longer need the size when allocating a new object as this is stored in
the class structure

--- dr changes 
Previous rev. maintained state on the communicator used for acking duplicate
fragments, but the communicator may be destroyed prior to successfull
delivery of an ack to the peer. We must therefore maintain this state
globally on a per peer, not a per peer, per communicator basis. 
This requires that we use a global rank on the wire and translate this as
appropriate to a local rank within the communicator.
