I removed my own shared_ptr<T> implementation, called ref_count<T> from libusipp. Sorry for breaking the API, but when I started the project, there was no shared_ptr<T> but now there is, and the standards version is of corse to prefer. It only comes to play when you register your own Layer2 RX or TX classes for example if you want to 'send' IP packets to a string or anything like that.

Excuse the brief README (as I just noticed), but the project is > 20y old and mainly serves internal purposes, such as qdns.

I also uploaded a new github signing key, as the old one expired.
