With this patch, all stateobject layout tests pass except for:

  fast/loader/stateobjects/pushstate-object-types.html = TEXT
  fast/loader/stateobjects/state-api-on-detached-frame-crash.html = TEXT

The first fails due to differences in the way we serialize Date and RegExp objects.

The second fails due to an exception thrown--not a crash, which the test was written to detect--while trying to access window.history.replaceState on a detached window (from an iframe that has been removed).

Ok.  I'm sad about backForwardNavigationScheme, but it looks like that's already there...

 590     bool isHashChange =
 591         !m_webFrame->frame()->loader()->history()->currentItem()->stateObject();

No need to line break in WebKit-land.

Thanks Adam.  Yes, backForwardNavigationScheme is the suck.  This change makes it suck a bit less since it will be seen by much less code; however, I really need to kill it somehow.  It should be pretty easy to do :)

Right, but line breaking like this is optional, no?  There are a number of similar line breaks in the same function and in this file.  I prefer to leave the line breaks for readability.

Yes, it's optional.
