Connecting - Disconnecting - Connecting ...

The overall design and implementation of the Blunt server seems to work ok, I can connect from other devices for pairing and getting Bluetooth services, repeatedly opening and closing connections. This is actually the biggest difference to the current Blunt implementation. Now it should be possible to have services running permanently, and not only when a component uses Bluetooth. Bluetooth Setup is also now starting to get more and more adapted to the Blunt server, which makes discovery problems hopefully a think of the past (the discovery time will be configurable as well). One important thing to sort out still is memory consumption, I think I need to add malloc/free tracing macros to the code.
