Ben Sander f80896d58b Make hipEvent_t thread safe. ...

Support re-recording of same event by different threads.

- Add criticalData structure to hipEvent_t, similar to mechanism used
  for streams, contexts, device.  Events are always locked
  after streams to avoid deadlock.
- ihipEvent_t::locked_copyCrit can be used to copy critical state
  including marker.  The critical state in the event can then
  be re-recorded.
- refactor hipEventElapsedTime.  Remmove stale debug code, native signal
  refs.
