Summary

0001894: Initial connection may time out if the host has lots of link-local addresses

Description

Possible fixes:

- Try initial connections faster (i.e. in parallel)

- Don't send link-local IPv6 addresses to the masterserver if the interface doesn't have a global address as well. Multicast discovery should still allow finding games from networks without internet connectivity.

- Sort addresses discovered by the masterserver/the netpuncher in front. May lead to sub-optimal address selection (like IPv4-over-DS-Lite instead of native IPv6).

- Somehow prioritize address choices. Prefer connecting to IPv6 addresses if both partners have public IPv6 addresses listed. Sort IPv6 addresses by longest matching prefix. Use IPv4 as fallback.

I added some prioritization now. However, the main issue was that the league didn't add its addresses properly (didn't update AddressCount), so those addresses were always ignored.
