this delegate seems to be unrelated to the popup blocker helper you've
implemented

The GetConstrainingContents does belong as a delegate of ... um ...
BlockedContentsTabHelper, or whatever that gets renamed to. I'll put the content
settings functions back. For now.

+class ContentSettingsTabHelperDelegate {
+ public:
+  // If |source| is constrained, returns the tab containing it.  Otherwise
+  // returns |source|.
+  virtual TabContentsWrapper* GetConstrainingContents(
+      TabContentsWrapper* source) = 0;
+
+  // Shows the Content Settings page for a given content type.
+  virtual void ShowContentSettingsPage(ContentSettingsType content_type) = 0;
+
+  // Shows the cookies collected in the tab contents.
+  virtual void ShowCollectedCookiesDialog(TabContents* tab_contents) = 0;
+
+ protected:
+  virtual ~ContentSettingsTabHelperDelegate();
+};
+
+#endif  // CHROME_BROWSER_UI_CONTENT_SETTINGS_CONTENT_SETTINGS_TAB_HELPER_DELEGATE_H_
