Summary: Tracelogger: add API routines to output the tracelogger events and dictionary → Tracelogger: add API routines to output the tracelogger events and dictionary from the profiler
Add a new class to extract tracelogger data using chunked buffers and use this to write the data out to the profiler JSON output. Copying the data in chunks lets us minimize our memory overhead when writing out to the profiler so a large array of millions of elements does not need to be allocated ahead of time.
