Detailed Description

CoAP over DTLS (CoAPs, RFC 7252 §9) - the bridge between the DTLS 1.3 server and the CoAP request handler.

CoAP secured with DTLS is the standard way to run CoAP over the open Internet (coaps://, UDP port 5684). This is the transport-neutral glue: it drives one DtlsConn through its handshake and, once established, unwraps each encrypted application record, hands the CoAP request to coap_server_process(), and re-wraps the response. The socket / per-peer routing lives in a thin front-end (dtls_server) on top; this file has no sockets, so it is host-testable with an in-test DTLS client, exactly like dtls_conn itself.
