/**********************************************************************
CMsgMsmqHdr - this header information is prepended with users header info
found in AuxData. This is primarily used by ack receivers so they can
can obtain the target queue and sent time of the message. There are a
couple of reasons why we store this information and not rely on msmq msg
props : 1 ) msmq cannot ensure that a returned message has not been
tampered with and 2 ) the target queue should be a logical name that a
user will understand, and not some format name that msmq will substitute
such as with public queues pathnames.
