Planning for o7 transport

[jmwample]

Features that I would like to support:

• UDP or TCP
• Optional Transport integrated Reliability / Ordering
  • If already using a reliable layer (i.e. TCP) you can disable the internal ordering / reliability
• Optional internal liveness
• Multiplex connections into streams
  • Control channel stream
• Extra data in handshake (client-to-server, and server-to-client)
• Session resumption
• Probe resistance
• Replay Resistance
• Customize-able Congestion Control
• Post Quantum Forward Secrecy
• Traffic shaping (padding / delays / cover)

In order to accomplish these goals the concept is to strip TLS1.3 from Quic and replace it with the o5 Handshake.
