 /*  WebSphere MQ in a nutshell
  *
  *   IBM WebSphere MQ (formerly IBM MQSeries) is an asynchronous proprietary messaging middleware that is
  *    based on message queues.
  *   MQ can run on more than 35 platforms, amongst which UNIX, Windows and mainframes.
  *   MQ can be transported on top of TCP, UDP, HTTP, NetBIOS, SPX, SNA LU 6.2, DECnet.
  *   MQ has language bindings for C, C++, Java, .NET, COBOL, PL/I, OS/390 assembler, TAL, Visual Basic.
  *
  *   The basic MQ topology is on one side the queue manager which hosts the queues.  On the other side the
  *   applications connect to the queue manager, open a queue, and put or get messages to/from that queue.
  *
  *   The MQ middleware allows very generic operations (send, receive) and can be compared to the
  *   socket API in terms of genericity, but it is more abstract and offers higher-level functionalities
  *   (eg transactions, ...)
  *
  *   The MQ middleware is not really intended to be run over public networks between parties
  *   that do not know each other in advance, but is rather used on private corporate networks
  *   between business applications (it can be compared to a database server for that aspect).
  *
  *   The wire format of an MQ segment is a sequence of structures.
  *   Most structures start with a 4-letter struct identifier.
  *   MQ is a fixed-sized format, most fields have maximum lengths defined in the MQ API.
  *   MQ is popular on mainframes because it was available before TCP/IP.
  *   MQ supports both ASCII-based and EBCDIC-based character sets.
  *
  *   MQ API documentation is called "WebSphere MQ Application Programming
  *   Reference"
  *
  *   See:
  *
  *       http://www-01.ibm.com/support/docview.wss?uid=pub1sc34606203
  *
  *       http://www-01.ibm.com/support/docview.wss?uid=pub1sc34694001
  *
  *   Possible structures combinations :
  *   TSH [ ID ^ UID ^ CONN ^ INQ ^ OD ]
  *   TSH MSH XQH MD [ PAYLOAD ]
  *   TSH [OD] MD [ GMO ^ PMO ] [ [XQH MD] PAYLOAD ]
  *   TSH [ SPQU ^ SPPU ^ SPGU ^ SPAU [ SPQI ^ SPQO ^ SPPI ^ SPPO ^ SPGI ^ SPGO ^ SPAI ^ SPAO]]
  *   TSH [ XA ] [ XINFO | XID ]
  *   where PAYLOAD = [ DH ] [ DLH ] [ MDE ] BUFF
  *
  *   This dissector is a beta version.  To be improved
  *   - Translate the integers/flags into their descriptions
  *   - Find the semantics of the unknown fields
  *   - Display EBCDIC strings as ASCII
  *   - Packets which structures built on different platforms
