Bug 991742 part 8. Remove the "aScope" argument of WebIDL/nsWrapperCache WrapObject() methods. r=bholley This patch was mostly generated with the following command: find . -name "*.h" -o -name "*.cpp" | xargs sed -e '/WrapObject(JSContext/ {; N; s/\(WrapObject(JSContext *\* *a\{0,1\}[Cc]x\),\n\{0,1\} *JS::Handle<JSObject\*> a\{0,1\}[sS]cope/\1/ ; }' -i "" and then reverting the changes that made to dom/bindings/BindingUtils.h, since those WrapObject methods are not the ones we're trying to change here, plus a bunch of manual fixups for cases that this command did not catch (including all the callsites of WrapObject()).
