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. This commit was SVN r9454.
