DISPATCH-759: Move freeing message and iterator out of core thread

----
> Core thread consumed deleting deliveries
> ----------------------------------------
>
> Key: DISPATCH-759
> URL: https://issues.apache.org/jira/browse/DISPATCH-759
> Project: Qpid Dispatch
> Issue Type: Bug
> Affects Versions: 0.8.0
> Environment: Fedora 25 laptop
> Single router, 8 worker threads, single receiver, single sender. Messages
> have 200 100-byte annotations.
> Reporter: Chuck Rolke
> Assignee: Chuck Rolke
>
> Without the annotations the router passes 33,000 messages per second. With
> the annotations the router passes about 500 messages per second. The whole
> router process is consumed creating and freeing messages.
> The issue exposes the fact that the router core thread is involved (90% cpu)
> in qdr_delete_delivery_CT. The core thread should not be involved in deleting
> deliveries and freeing messages.
