Initial import of headless systrace analysis.

Can dump the following on a per-process/activity basis:
- Time the process was running / activity in the foreground
- # of frames rendered, and their performance
- # of direct reclaims
- Amount of time spent on each CPU for key threads
- CPU frequency distribution
