Title: Experimental chrome:tracing support.

Seems to work, but not testing backwards. Simple hacky hookup for
extracting the data via some exposed APIs. Simple extension showing off
getting the data, and plumbing it into trace events.
Unfortunately without an accurate timebase the data isn't so useful.
This will remain experimental for now.
