Those are ngtcp2 API changes that need to be updated in lokinet; it currently uses an older version of ngtcp2 in external/ngtcp2. Properly fixing this to build with a more recent version (and proper support for using/linking to a system ngtcp2) should come from the upcoming merge of libquic into Lokinet, but likely isn't a trivial patch.

Apparently not everyone has heard that API compatibility is desirable LOL
