tls: dtls initial implementation
Type: feature
Basic dtls transport protocol implementation that relies on openssl
wire protocol implementation. Retries/timeouts not yet supported.
To test using vcl test apps, first ensure all arp entries are properly
resolved and subsequently:
server: vcl_server -p dtls 1234
client: vcl_client -p dtls <server-ip> 1234 -U -N 2000000 -T 1460 -X
