ContentConfirmInfoBarDelegate is a ConfirmInfoBarDelegate which knows one
instance of WebContents.
It will eventually live in components/infobar/content/browser/.

The WebContents pointer is reset when the new CleanUp() function is called.
The CleanUp function has been added mainly for this purpose.
