update_engine: Merge remote-tracking branch 'cros/upstream' into cros/master

Done with:
git merge cros/upstream --commit -s recursive

- Added EC key support and its unittests.
- Resolved a conlict on error codes. Since Android versions are not
  uploading any UMA metrics, I gave the priority to the Android version
  Since they can't be changed.
- Changed the openssl functions to get1 version (from get0) version
  because of a current issue with gale. Once the issue is resolved we
  need to change them back.
- Some remaining styling issues fixed by clang-format

BUG=b:163153182
TEST=CQ passes
TEST=unittests
