patch

js::UnwrapObject currently has the following behavior:

If you pass an outer window directly to it, it returns the inner window ("unwrapping" the outer).

If you pass a security wrapper to it, it will unwrap up to the outer window, but won't unwrap it. This is useful for the case where we want to peak under the security wrappers, but don't actually need the native out of the JS object.

It turns out that it'd be useful to have an API that lets us get the innermost object. This patch adds that API and uses it in the two existing places that it seems to be useful.

Backed out in https://hg.mozilla.org/integration/mozilla-inbound/rev/d7c7ea755e54 - about 90 short of passing make check.

Updated patch

Carrying forward review: I missed a use of UnwrapObject in js/src/shell/js.cpp. Everything else is the same and the fix is trivial.
