Only qxl covered for this RfC, other modules will follow once the basics are hashed out. v3: - handle initialization of modular tracepoints. TODO: Enabling modular tracepoints via -trace cmd line doesn't work yet. Guess we need to store the list somewhere for later re-processing. Error handling is tricky, specifically the "tracepoint doesn't exist" error. Suggestions / ideas are welcome.
