[libvirt] [libvirt-java] [PATCH 0/2] Ensure JNA callbacks cannot be GCed

Hi. This is a small patch set to fix a few issues I've discovered while testing Claudio's patch set. The first patch is trivial, it adds the ConnectionCloseListener interface and corresponding enum, which were missing. The second patch ensures that the JNA callbacks cannot be garbage collected whilst still registered with the libvirt C library. Durring testing, I was finding that events would stop working. Wireshark showed the remote daemon sending the event and some time spent tracing through the libvirt calls led me to discover that the JNA callback objects were being GCed. The JNA documentation states that a reference to the Callback object must be held whilst it is in use by the C layer. This patch updates the map of event listeners to also hold a reference to the callback object.
