CONNECT-IP encapsulated client support

This CL adds a new mode to masque_client that allows testing HTTP/3 over CONNECT-IP (as opposed to HTTP/3 over CONNECT-UDP). It creates UDP and IP headers on the fly.

This code isn't used in production, it solely exists for IETF interop and therefore does not have adequate test coverage or flag protection. Those will be added in the future when we migrate the code out of the masque directory.

QUICHE stands for QUIC, Http, Etc. It is Google‘s production-ready implementation of QUIC, HTTP/2, HTTP/3, and related protocols and tools. It powers Google’s servers, Chromium, Envoy, and other projects. It is actively developed and maintained.

There are two public QUICHE repositories. Either one may be used by embedders, as they are automatically kept in sync:

To embed QUICHE in your project, platform APIs need to be implemented and build files need to be created. Note that it is on the QUICHE team's roadmap to include default implementation for all platform APIs and to open-source build files. In the meanwhile, take a look at open source embedders like Chromium and Envoy to get started:

QUICHE is only supported on little-endian platforms.
