This commit adds a new type to magicsock, epAddr, which largely ends up replacing netip.AddrPort in packet I/O paths throughout, enabling Geneve encapsulation over UDP awareness. The conn.ReceiveFunc for UDP has been revamped to fix and more clearly distinguish the different classes of packets we expect to receive: naked STUN binding messages, naked disco, naked WireGuard, Geneve-encapsulated disco, and Geneve-encapsulated WireGuard. Prior to this commit, STUN matching logic in the RX path could swallow a naked WireGuard packet if the keypair index, which is randomly generated, happened to overlap with a subset of the STUN magic cookie.
