This leak is easily triggered by the HTTP1 adaptor but can also be triggered using plain AMQP.

This is a shutdown leak.  This occurs when a qdr_delivery_t is left on the link's updated_deliveries list at the point where the shutdown occurs.

Since this is a shutdown leak I will add a suppression to the lsan.supp list for now - this Jira remains open until the issue is actually fixed.
