Original issue's description:
> Enable subframe FrameNavigationEntries by default.
>
> This is a major change to the navigation logic in Chrome, making
> the browser process responsible for selecting subframes to
> navigate.  Each NavigationEntry now has a tree of
> FrameNavigationEntries representing each frame in the page, and
> these frame entries track per-frame PageState.
>
> HistoryController in content/renderer is no longer used, since
> equivalent code in NavigationController in content/browser now
> determines which frames to navigate.
>
> This CL is designed to be easy to revert if regressions are
> found, though the new path has been in use on 50% of Canary and
> Dev channels for a while.
>
> BUG=236848
> TEST=Existing tests pass.
