Optimizes the creation of a returned payload message by duplicating the original message and then updating the small number of fields that need to be adjusted, rather than building the new message header from scratch. In addition, certain operations that are not always required are relocated so that they are only done if needed. These optimizations also have the effect of addressing other issues that were present previously: 1) Fixes a bug that caused the socket send routines to return the size of the returned message, rather than the size of the sent message, when a returnable payload message was sent to a non-existent destination port. 2) The message header of the returned message now matches that of the original message more closely. The header is now always the same size as the original header, and some message header fields that weren't being initialized in the returned message header are now populated correctly -- namely the "d" and "s" bits, and the upper bound of a multicast name instance (where present).
