We have these DOMLinkAdded/Removed events that we fire on <link> elements... Unfortunately, we fire them in ways content can see, while stomping on the DOM namespace and all.  Not much we can do about the latter now, I think, but we should fix the former.
So we want to fire the events to chrome event handler, but using <link>
as the target.

Indeed, like so

Some null checks needed here, especially now that this may get called async.

Nit, NS_ENSURE_STATE(node);

r+sr=me, with null checks. I guess those are needed on branch too,
so perhaps a separate bug which blocks this one and this could land after
that one.

Bah, null checks are there.
