Re-do r15244 again.

Originally reviewed at http://codereview.chromium.org/100353

Eliminate webkit/glue/webhistoryitem* in favor of adding a
NavigateBackForwardSoon method WebViewDelegate.  This moves
all of the hacky details of how we intercept "history.{back,
forward,go}" into the webkit layer.  My eventual plan is to
teach WebCore how to make this not hacky.

In this version of the CL, TestWebViewDelegate performs the
back/forward navigation directly in NavigateBackForwardSoon
instead of using PostTask to delay it.  I'm doing this to
minimize regressions so that I can hopefully get the rest of
this CL landed.

I also already made the changes to WebKit to force history.
{back,forward,go} to be processed asynchronously.

Finally, it was necessary to move DumpBackForwardList out of
webkit_glue.cc since it was using itemAtIndex to generate
those results, and now that we return synthetic URLs for
that function, the results were very wrong.  The fix is to
move DumpBackForwardList into TestShell so that it can more
directly inspect the TestNavigationController.  Now, it is
necessary for webkit_glue.h to expose a function to dump
a content state string (aka a WebCore::HistoryItem).
