Experimental HTTP/3 tooling for Java / JVM systems.

Motivation / bets:

• I want to properly understand HTTP/3 and WebTransport (and therefore also QUIC), and implementing from scratch is a good way to do that
• Both HTTP/3 and WebTransport will offer very interesting new capabilities to websites and apps
• WebTransport appears to require HTTP/3 at every layer (including LB <-> application), so having it readily available for Java apps is important

Other ideas:

• Thorough automated testing is important, so use or build something like h2spec for verification
• If the project goes well, it could be packaged up as something to build clients on
  • Or maybe even the basis for an HTTP/3-only client
• Loom means it can be declarative, and hopefully easier to implement and understand the threading model (eg thread per stream)

Documentation:

• HTTP/3 RFC: https://datatracker.ietf.org/doc/html/rfc9114
• QUIC RFC: https://datatracker.ietf.org/doc/html/rfc9000
• WebTransport MDN: https://developer.mozilla.org/en-US/docs/Web/API/WebTransport
