Bobby Holley 01f304382c Bug 860941 - Separate the handling of |dialogArguments| and |arguments|, and use IDL for the |dialogArguments| getter. r=jst 
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.
