Describe the feature you'd like supported

The Tongsuo project has introduced a QUIC API feature branch:
https://github.com/Tongsuo-Project/Tongsuo/tree/dev/quicapi

This feature is expected to be included in tongsuo-8.5.0-pre2 and subsequent releases.

Note (unverified): When integrating with XQUIC, it may be necessary to add
add_definitions(-DOPENSSL_SUPPRESS_DEPRECATED) to CMakeLists.txt to suppress deprecation
warnings from OpenSSL 1.x APIs being promoted to errors.
