Merge remote-tracking branch 'goog/sc-dev-plus-aosp' into merge-sc-dev-plus-aosp-then-rvc-qpr-dev-plus-aosp

This CL merges sc-dev-plus-aosp into mainline-prod. It picks up
changes that:
- Were merged into sc-dev and automerged into sc-dev-plus-aosp
- Were merged into aosp master while sc-dev-plus-aosp was on the
  path between AOSP and master.

It does not pick up changes that were merged into aosp before
sc-dev-plus-aosp was on the merge path from AOSP to master. One
such very simple CL is aosp/1554765.

There were no merge conflicts.

Current diffstat with aosp/master is:

 161 files changed, 2923 insertions(+), 4005 deletions(-)

This includes 1800 lines of translations added in 72 files like
