Andrew Halberstadt f94d7e71d8 Bug 1034290 - Use structured log output for test results in reftest, r=jmaher 
Structured logs bring many benefits. We can stop parsing the logs for magic strings, we
can modify the format without breaking things, and we can stream results into systems like
ActiveData. The structured logs originate primarily in reftest.js. StructuredLog.jsm is
used to generate the JSON-based log stream. Finally OutputHandler in the python harness
reads structured output from stdout, and formats it into human readable form.
