If Sync is (likely) not configured, the only loaded JS is for the XPCOM
service itself.
The UI code is now smart enough to initialize the Sync service if it
isn't yet loaded. This addresses bug 825728.
The assertions in nsINode and nsWrapperCache are to eagerly catch
failures to override those methods.
The classinfo change for XULTreeBuilder is needed because one of those
is returned via an nsIXULTemplateBuilder attribute on XULElement.
Alternately, I could mark it notflattened in Bindings.conf, but Enn
said he prefers this anyway.
The change to the QI impl in BindingUtils is needed because when
XPConnect converts an IID from C++ to JS it makes is an nsJSID, not an
nsJSIID. We've run into this before, sadly.
I removed "id" from nsIDOMXULElement because it's already on Element.
I suppose I could have left it there, but this seems cleaner.
The nsJSIID::HasInstance changes are needed to support XBL-implemented
interfaces. Sadly, this does mean that if the underlying object QIs
to something but we didn't put those props on the WebIDL we'll end up
testing true for instanceof but not exposing the props. I don't see
an obviously better way. We should work on killing off uses of
"instanceof someinterface".
The browser.js change is needed to avoid throwing exceptions during
browser-chrome tests that are now getting reported because our
swapFrameLoaders is no longer an XPConnect method.

There's a browser-chrome test that does this, which means that _all_ subsequent
browser-chrome tests inherit it. So depending on the ordering of cases in
WrapperFactory, we might end up using a CrossCompartmentWrapper rather than an
XrayWrapper, meaning that stuff like nodePrincipal doesn't work anymore.
The semantics of UniversalXPConnect are now entirely dicatated by what makes
our test suite go green. So let's not force ourselves to bend over backwards
during wrapping to handle this case. And let's fix that stupid test while
we're at it.
