We leave the stuff under api/ alone for now, since we need to be able to ship
it as a standalone thing.
tools/post-receive wasn't using the function anyway.
For push to master: Push this commit, update post-receive per instructions at
the top of that file, then push the rest of the branch to confirm that the hook
still works.
No manual instructions for prod.
