Fix fast/loader/reload-policy-delegate.html...

Fix tests that depend on setCustomPolicyDelegate and waitForPolicyDelegate.

Changes:

1-  Need to support a second parameter to setCustomPolicyDelegate that
controls whether subsequent loads are permitted or not.  Previously,
we would always deny any subsequent loads.

2-  Need to change the string that we produce when writing out the URL
that is impacted by a custom policy delegate.  We need to write out only
the filename part of the URL.  (We need to do this only for file:// URLs.)

3-  Add LayoutTestController::waitForPolicyDelegate and corresponding
method on TestWebViewDelegate.

4-  Improve the way we reset the TestWebViewDelegate.  Now, instead of
having support for reseting individual fields, we just reallocate the
delegate.  This requires adding a SetDelegate method to WebView.

I couldn't help myself... I extended this patch to include support for
waitForPolicyDelegate.  Please take a look :)

Even better. LGTM.

You should try not helping yourself more often :)
