/**
* Notifies the history system that the page loading via aOldChannel
* redirected to aNewChannel. Implementations should generally add the URI for
* aOldChannel to history for link coloring, but are advised not to expose it
* in the history user interface. This function is preferred if
* nsIGlobalHistory3 is available. Otherwise, nsIGlobalHistory2.addURI should
* be called with redirect=true.
*
* This function is preferred to nsIGlobalHistory2.addURI because it provides
* more information (including the redirect destination, channels involved,
* and redirect flags) to the history implementation.
*
* For implementors of nsIGlobalHistory3: The history implementation is
* responsible for sending NS_LINK_VISITED_EVENT_TOPIC to observers for
* redirect pages. This notification must be sent for history consumers for
* all non-redirect pages.
*
* @param aToplevel whether the URI is loaded in a top-level window. If
* false, the load is in a subframe.
*
* The other params to this function are the same as those for
* nsIChannelEventSink::OnChannelRedirect.
*
* Note: Implementors who wish to implement this interface but rely on
* nsIGlobalHistory2.addURI for redirect processing may throw
* NS_ERROR_NOT_IMPLEMENTED from this method. If they do so, then callers
* must call nsIGlobalHistory2.addURI upon getting the
* NS_ERROR_NOT_IMPLEMENTED result.
