> Mixed Content: Make MixedContentChecker completely static.
> 
> This patch completes the transition away from MixedContentChecker as an
> object with state, into a world where it just provides static methods.
> This should clear up the interface, and make migration to RemoteFrame
> a bit simpler.
> 
> After this patch, we no longer hang a MixedContentChecker object off
> of FrameLoader, nor does MixedContentChecker need to hold a reference
> to a frame. Everything we need to do the checks can be done by passing
> values into the checker methods.
> 
> Note also that this patch deletes a number of expectation files: these
> are testharness.js tests, which shouldn't have expectations
> committed into the repository. Rather than modifying them, this patch
> removes them.
> 
> As a drive-by, this also corrects the FormsSubmitted counter.
> It ought to count all form submissions as "FormsSubmitted", and mixed
> submissions as a subset thereof (e.g. 5 form submissions,
> with 2 of them mixed would result in FormsSubmitted: 5,
> MixedContentFormsSubmitted: 2, as opposed to the current 3 and 2).
