From: Robert Gemmell <robbie@apache.org>
Date: Sun, 26 Aug 2012 21:25:08 +0000
Subject: QPID-4250: ensure producer creation on 0-8/0-9/0-9-1 connections
 respects the qpid.declare_exchanges system property. Add systest to highlight
 the issue and verify the fix. Add constants for the system properties.
