David Howden d0aafc73d5 trace: fix races on concurrent Trace method calls ...

This change protects fields mutated by Trace methods with a mutex.
In particular it fixes races caused by concurrent calls to IsError,
and viewing active traces in /debug/requests.

Includes changes from CL/67730.

Updates golang/go#24231
