Retrieve the frontend destination address for a QUIC connection. This address is retrieve from the first received datagram and then stored in the associated quic-conn. This feature relies on IP_PKTINFO or affiliated flags support on the socket. This flag is set for each QUIC listeners in sock_inet_bind_receiver(). To retrieve the destination address, recvfrom() has been replaced by recvmsg() syscall. This operation and parsing of msghdr structure has been extracted in a wrapper quic_recv(). This change is useful to finalize the implementation of 'dst' sample fetch. As such, quic_sock_get_dst() has been edited to return local address from the quic-conn. As a best effort, if local address is not available due to kernel non-support of IP_PKTINFO, address of the listener is returned instead. This should be backported up to 2.6.
