Now that XBL scopes are here to stay (no more pref), we can remove all the machinery that makes SOWs dynamic. We still need SOWs until bug 825392 is fixed, but they can now be totally opaque. One side effect of this patch is that, due to our usage of Opaque, we now allow CALL on SOWs. But this shouldn't be a problem, because SOWs are used for anonymous elements which are not callable (and we probably wouldn't mind it even if they were).
