impl_qpid doesn't ACK messages

[Russell Bryant]

After an incoming message has been processed, impl_qpid should call acknowledge() on the session. Since it doesn't right now, this results in increasing memory usage as a queue of unacked messages grows unbounded.

    Add missing ack to impl_qpid.

    Fix bug 1012374.

    Johannes Erdfelt pointed out that impl_qpid wasn't acking messages that
    it received. This turned out to be a nasty oversight, resulting in
    unbounded message queue growth inside of the python-qpid library. This
    fixes it.

Please find the attached test log from the Ubuntu Server Team's CI infrastructure. As part of the verification process for this bug, Nova has been deployed and configured across multiple nodes using precise-proposed as an installation source. After successful bring-up and configuration of the cluster, a number of exercises and smoke tests have be invoked to ensure the updated package did not introduce any regressions. A number of test iterations were carried out to catch any possible transient errors.

Please Note the list of installed packages at the top and bottom of the report.
