routing-yggdrasil: add package

Yggdrasil builds end-to-end encrypted networks with IPv6. Beyond the similarities with cjdns is a different routing algorithm. This globally-agreed spanning tree uses greedy routing in a metric space. Back-pressure routing techniques allow advanced link aggregation bonding on per-stream basis. In turn, a single stream will span across multiple network interfaces simultaneously with much greater throughput.
