where will the code that call this reside, i.e. in content/ or chrome/ ? if in
content/, this doesn't need to be exposed on the public API

really good point! until a couple of days ago :) this was called by an object
that just got renamed / moved to ContentView donwstream.

I'll fix that, but just to make it right: I see a few places that static_cast a
RenderViewHost down to a RenderViewHostImpl, and some other places that use the
RVH to directly send the IPC message. which one is the preferred way?

(our ContentsView, which is essentially a conduit to/from the java side, has a
WebContents, which gives it access to a RVH)
