What's going on here? This changes impacts all renderers not just BrowserPlugin.

Well that's the point of using a new message; it won't affect any existing
functionality.
The purpose of the message here is to let the embedder know when the native
drag_host_ has ended the drag event (so that the embedder can let the guest know
the drag event is done and the guest can end it's drag event too (and restore
user input)). It's the only platform agnostic place to put this kind of message.
