This patch publishes the work done until now for Python 3.0 compatibility. Still a lot to be done. When possible, we use 3.0 features in Python 2.6, easing development and testing, and exposing internal changes to a wider audience, for better test coverage. Some mode details: http://www.jcea.es/programacion/pybsddb.htm#bsddb3-4.7.2
