This patch is bigger than I'd like it to be, but there are a lot of interlocked dependencies and I eventually decided it was easier to just lump it together. The semantics of |showModalDialog|/|window.dialogArguments| (an web-exposed HTML5 feature) and |openDialog|/|window.arguments| (a XUL-proprietary feature) are quite different. The former is essentially a security-checked JSVal, while the latter gets converted into an array. We handled them together in the old world, which led to a lot of confusion and muddled semantics. This patch separates them. This patch also eschews the roundabout resolve hook for dialogArguments in favor of returning them directly from the XPIDL getter. This better matches the behavior in the spec, especially because it allows dialogArguments to live on the outer as they're supposed to, rather than the first inner that happens to end up in the docshell. All in all, this should make this all very straightforward to convert WebIDL when the time comes. The current spec on the origin checks here is pretty fictional, so I've filed https://www.w3.org/Bugs/Public/show_bug.cgi?id=21932 to fix it. This patch should more or less preserve the current security behavior.
