tracing: Unbreak user events

The user events was added a bit prematurely, and there were a few kernel
developers that had issues with it. The API also needed a bit of work to
make sure it would be stable. It was decided to make user events "broken"
until this was settled. Now it has a new API that appears to be as stable
as it will be without the use of a crystal ball. It's being used within
Microsoft as is, which means the API has had some testing in real world
use cases. It went through many discussions in the bi-weekly tracing
meetings, and there's been no more comments about updates.

I feel this is good to go.
