This method captures all application/pdf streams, loads the viewer and passes the stream to the PDF.js viewer. This commit shows a proof of concept using the chrome.streamsPrivate API. Advantages of new method: - Access to the response body of the original request, thus fewer network requests. - PDFs from non-GET requests (e.g. POST) are now supported. - FTP files are also supported. Possible improvements: - Use declared content scripts instead of dynamic chrome.tabs.executeScript. This allows the extension to render the viewer in frames when the extension is disallowed to run executeScript for the top URL. - Use chrome.declarativeWebRequest instead of webRequest, and replace background page with event page (don't forget to profile the difference & will the background/event page still work as intended?).
