Start of 1.8.x development. Sorry for the big commit, but in fact it should have been bigger.

The fact that we now have an active developer on branch ipv6 made me do this before I would like to.
The idea here is to hide libupnp internal data structures from the outside world so that
developers can be free to change them without breaking the interface. There is still some work to do
before a formal release, but the samples (device and control point) should be working.
