1. initialize the MTU discoverer when processing the transport parameters …

   On the client side, we always use the configured packet size. This comes
   with the risk of failing the handshake if the path doesn't support this
   MTU. If the server sends a max_udp_payload_size that's smaller than this
   size, we can safely ignore this: Obviously, the server still processed
   the (fully padded) Initial packet, despite claiming that it wouldn't do
   so.
   
   On the server side, there's no downside to using 1200 bytes until we
   received the client's transport parameters:
   * If the first packet didn't contain the entire ClientHello, all we can
   do is ACK that packet. We don't need a lot of bytes for that.
   * If it did, we will have processed the transport parameters and
   initialized the MTU discoverer.
