  Impact: implement new tracing timestamp APIs

  Add three trace clock variants, with differing scalability/precision
  tradeoffs:

  - local: CPU-local trace clock
  - medium: scalable global clock with some jitter
  - global: globally monotonic, serialized clock

  Make the ring-buffer use the local trace clock internally.
