DISPATCH-628: Multiple connections per autoLink and linkRoute overwrites
connection handle
This ensures that an autolink and linkroute can be bound to more than one
connection. The assert checking this is disabled in optimized builds and was
never triggered.

> Key: DISPATCH-628
> URL: https://issues.apache.org/jira/browse/DISPATCH-628
> Project: Qpid Dispatch
> Issue Type: Bug
> Components: Router Node
> Reporter: Ulf Lilleengen
> Assignee: Ted Ross
> Fix For: 0.8.0
>
>
> When implementing https://github.com/apache/qpid-dispatch/pull/111 I stumbled
> across an issue with an autoLink or linkRoute only being able to refer to
> more than 1 connection, which I assumed would originaly cause an assert in
> route_control.c:350 to trigger when I configured an autoLink to trigger on a
> containerId and use the same container id when sharding a queue.
> Since the assert didn't trigger, I assumed that I must have misread the code,
> but nontheless as part of the patch I made it possible for a
> linkRoute/autoLink to be associated with multiple connections.
> Recently, I have seen some router crashes when scaling up and down queues in
> EnMasse, and I just figured that the reason for this assert not triggering is
> that it is disabled in the RelWithDebInfo configuration.
> If built without optimizations (Debug), I'm able to trigger the issue with
> the configuration in http://people.redhat.com/~ulilleen/bugs/routerconn/
> To trigger, I startup the router and broker as so:
> qdrouterd -c router_incoming.conf
> export MESSAGING_SERVICE_HOST=localhost
> export MESSAGING_SERVICE_PORT_INTERNAL=55673
> export QUEUE_NAME=myqueue
> export CONTAINER_ID=myqueue
> ./br/bin/simplebroker &
> ./br/bin/simplebroker
> I have extracted the patch from DISPATCH-476 and will create a PR with it.
