net/udprelay: start of UDP relay server implementation (#15480)
This commit implements an experimental UDP relay server. The UDP relay
server leverages the Disco protocol for a 3-way handshake between
client and server, along with 3 new Disco message types for said
handshake. These new Disco message types are also considered
experimental, and are not yet tied to a capver.

The server expects, and imposes, a Geneve (Generic Network
Virtualization Encapsulation) header immediately following the underlay
UDP header. Geneve protocol field values have been defined for Disco
and WireGuard. The Geneve control bit must be set for the handshake
between client and server, and unset for messages relayed between
clients through the server.
