Caused by <https://trac.webkit.org/changeset/257472>. Need to leave a stub behind to keep old Safari working.

We should fix this so people outside Apple can continue to work on WebKit.

In past cases like this one we left the thing out of the header file and put it in the .cpp file with a comment like the one above. We should put it at the top of the .cpp file instead of here.
