Chromium usually calls SetInstance once per process. However, when run in single process more renderer threads will try to set the instance after the browser process already has done so. This allows them to fail gracefully without asserting.

This patch includes a modified version of Chrome's trace_event.h, which provides
tracing macros that can easily integrate into the about://tracing framework.
Currently the macros link to a default implementation of the (narrow) tracing
class SkDefaultEventTracer which does nothing; next step will be to have Chrome
subclass the SkEventTracer with a shim that bolts Skia's trace events to its own,
allowing Skia's trace events to show up in about://tracing.
I've verified that this file builds properly, and when I added a simple scoped
TRACE_EVENT0 to SkCanvas::drawRect, along with some debug prints in the NOP
implementation of tracing, I saw what I expected printed to the screen.
