Beau Belgrave	17b439db21	tracing/user_events: Ensure bit is cleared on unregister ... If an event is enabled and a user process unregisters user_events, the bit is left set. Fix this by always clearing the bit in the user process if unregister is successful. Update abi self-test to ensure this occurs properly.

Beau Belgrave	60b1af8de8	tracing/user_events: Add ABI self-test ... Add ABI specific self-test to ensure enablements work in various scenarios such as fork, VM_CLONE, and basic event enable/disable. Ensure ABI contracts/limits are also being upheld, such as bit limits and data size limits.
