I don't see anywhere in the bug or CL description that indicates this should be
adding a new extension API function, nor anywhere that defines this function so
it could be exposed to an extension.  Is this intentional/necessary?

This API was changed because test suite browsing_data_test.cc was failing. And I
was not sure if there is a way to work around these failures. But as msramek@
confirmed it is not necessary to add to the extension API, and there is another
way to make the tests pass, I am reverting these changes, and not implementing
this API change. Sorry for the confusion, I was waiting to hear from msramek@
before updating the cl.
