[libvirt] PATCH 0/5: connection cloning support (WIP)

This series is a work-in-progress set of patches implementing connection cloning. The idea is that if you want to use a connection form multiple threads, you could do virConnectPtr copy = virConnectClone(conn) and use 'copy' from the other thread. This avoids the problem of having to make all the virError handling stuff thread-local whic is the blocker for allowing real mutlti-thread access to a single virConnectPtr object. I believe this cloning support should be sufficient for the Java bindings need to use a thread for its event loop. The idea being that if you wanted to use an event loop in a background thread, you'd create a cloned object for use event loop triggered callbacks like domain events notifications. I'd still like to do some experiments later making the single virConnectPtr fully thread safe, but that'll take a little more time. I'm hoping this cloning will address the Java needs right now...
