Checked in.

It compiled with only one warning on my FreeBSD 3.4 machine:

	../packet-mq.c:731: warning: unused variable `iVersionUID'

There's a comment in the code that

	The iVersionID is available in the previous ID segment, we
	should keep a state

so I'll leave that variable, and the warning, there for now as a
reminder.

Note that as this is running over TCP, there's not necessarily a
guarantee that

	1) an MQ message will fit entirely in one TCP segment

or

	2) there will be only one MQ message per TCP segment

If it's not to difficult to determine the length of an MQ message by
looking at the first few bytes of the message, it wouldn't be too hard
to make it use "tcp_dissect_pdus()" to handle those issues.
