Modify quic_dgram_parse() to stop passing it a listener as third parameter. In place the object type address of the connection socket owner is passed to support the haproxy servers with QUIC as transport protocol. qc_owner_obj_type() is implemented to return this address. qc_counters() is also implemented to return the QUIC specific counters of the proxy of owner of the connection. quic_rx_pkt_parse() called by quic_dgram_parse() is also modify to use the object type address used by this latter as last parameter. It is also modified to send Retry packet only from listeners. A QUIC client (connection to haproxy QUIC servers) must drop the Initial packets with non null token length. It is also not supposed to receive O-RTT packets which are dropped.
