Fix up python bindings for new event callbacks
The generator was disabled for the new event callbacks, since they need to be hand written. This patch adds the C and python glue to expose the new APIs in the python binding. The python example program is extended to demonstrate of the code * python/libvirt-override.c: Registration and dispatch of events at the C layer * python/libvirt-override-virConnect.py: Python glue for events * examples/domain-events/events-python/event-test.py: Demo use of new event callbacks
