TraceProcessor: add support for complete JSON events
Will require some follow-up clean ups, but in the meanwhile
brings us into a nice state w.r.t. digesting legacy traces.
This CL:
- Extracts thread and process names from metadata events.
- Creates a full stack of slice using both duration and complete events
(TRACE_EVENT_BEGIN/END(...) and TRACE_EVENT(...))
- Exposes pids and tid in the process and thread vtables.
- Refactors the ProcessTracker to support identifying threads.
by the pid+tid tuple.
- Improves the hashing of the string pool using 32-bit FNV-1a.
