Add trace_to_text
To estimate overhead of perfetto we would like to use... perfetto!
To allow for this reintroduce the 'trace_to_text' binary from the demo
which takes in a Trace and outputs systrace formatted text viewable
in the TraceViewer.
Other changes in this CL:
- Introduce a 'Trace' proto.
This proto is just a repeated field of TracePackets
- Modify perfetto_cmd to output a Trace rather than just all the
TracePackets back to back.
- To allow for this perfetto_cmd has a new dep on protozero.
- Fix a bug in ftrace_controller.cc where we implemented the generation
count for each periodic task we started rather than once for each set
of periodic tasks.
