This doesn't do anything in the default process-per-task mode, because
those child tasks exit using _exit(), which doesn't trigger the event
tracer destructor to flush.
I don't remember exactly why I exit with _exit(), so I'm going to have
to follow up on that. But written this way as I think I'm at least
initializing the tracing in the right place for each process for the
future.
In threaded (-j -1) and serial (-j 0) modes, everything seems to work
great.
I'm also thinking I might add a tracer like the SkDebugf tracer but
using ok_log(), which handles interlaced logging from concurrent tasks
better than vanilla SkDebugf.
Example:
ninja -C out ok; and out/ok gm 8888 filter:search=fontmgr_bounds trace -j -1

Not yet thread safe (so it forces threading off).
Builds JSON on the fly, so overhead is certainly bad.
Plan to fix all of that, but this at least "works".
There is now one tracing flag: 'trace'.
- 'debugf' installs the SkDebugf tracer.
- 'atrace' installs the Android ATrace tracer.
- Any other value is interpreted as a filename, and
produces a JSON file for chrome://tracing.
All three modes work in DM, nanobench, and Viewer.
