augment quic demos to support ipv4/6 connections
Because the quicserver utility supports expressly listening in ipv4/6
mode, its possible/likely that the server will listen on an ipv4
address, while the clients will connect via ipv6, leading to connection
failures.
Augment quic demo clients to afford them the same -6 option that the
server has so that connection family can be co-ordinated
