This PR allows storing a flight of packet, eg. all packets that were sent by a PUT between two steps, in the knowledge. This flight could then be queried and used in a trace as a
Vec<Message>
. This PR also adds the ability to send a Flight of packets in a trace step, which allows to send multiple packets at once.This is needed to make the traces less dependent of implementation choices and to be resilient if some implementations choose to fragment their packets in different ways.
The first use case is to create traces that work both for OpenSSL/WolfSSL/LibreSSL and BoringSSL, the latter fragmenting his handshake messages differently than the formers.
