Review request for qpid, Gordon Sim, michael goulish, and Ted Ross.
Summary
-------
The fix replaces the per-broker federation uuid with a unique uuid for each
queue created.
I'm not aware of anything that is sensitive to the current format of the bridge
queue name, and expects to find a federation uuid in the name.

This addresses bug qpid-3773.

> The following valid configuration results in a failure to create a second

> ./qpidd --auth no --no-data-dir -p 9999 &

> [kgiusti@localhost src (trunk)]$ qpid-config -a127.0.0.1:9999 add exchange

> [kgiusti@localhost src (trunk)]$ qpid-route -s route add 127.0.0.1:9999
> 127.0.0.1:8888 ex1 "#"
> This *should* result in two bridge queues being created on 127.0.0.1:8888;
> one queue for the route to :7777, the other for the route to :9999.
> What actually happens is one queue is created:
> [kgiusti@localhost src (trunk)]$ qpid-stat -q 127.0.0.1:8888

> This is due to the way the broker generates the name for the queue. The
> format of the name is "bridge_queue_" + channel# + broker's federation uuid.
> In the failure case, the channel # happens to be the same for both routes,
> which results in duplicate names for different queues.
