This set of patches adds a way for the perfetto command line client to
save a trace to a hardcoded location,
/data/misc/perfetto-traces/incident-trace, and call into incidentd to
start a report, which will include said trace in a new section.
This is not a long-term solution, and is structured to minimize changes
to perfetto and incidentd. The latter is currently architected in a way
where it can only pull pre-defined information out of the system, so
we're resorting to persisting the intermediate results in a hardcoded
location.
This will introduce at most two more linked files at the same time.

(cherry picked from commit 09a847902f)
incident_helper
It is an executable used to help parsing text format data to protobuf.
How to build, deploy, unit test
For the first time, build the test and create an empty directly on device:
root$ make -j incident_helper_test && adb shell mkdir /data/nativetest64/incident_helper_test
Run the test on a device
root$ mmm -j frameworks/base/cmds/incident_helper && \
adb push $OUT/data/nativetest64/incident_helper_test/* /data/nativetest64/incident_helper_test/ && \
adb shell /data/nativetest64/incident_helper_test/incident_helper_test 2>/dev/null
How to adapt proto changes
If add a new proto file, add it in Android.bp under frameworks/base/ and make incident helper
root$ make -j48 incident_helper
