This is required to land https://codereview.chromium.org/392993005/.
I shall create a follow up CL to remove the overridden methods. PTAL.

Is there a bug tracking this work and describing the test plan?  If not, file
one.  If there is, link it in the description.

File content/renderer/render_view_impl.cc (right):

https://codereview.chromium.org/485103005/diff/1/content/renderer/render_view...
content/renderer/render_view_impl.cc:3957: void
RenderViewImpl::registerProtocolHandler(const WebString& scheme,
annotate with a comment or something that the registerProtocolHandler versions
that take a base_url are going away, otherwise this looks like needlessly
duplicate code.  a good way would be to add a comment like this:

// TODO(your user name): Remove once blink patch lands. http://crbug.com/21345

to the functions you plan to delete soon
