Highlights of changes:

1. Added entry to ResourceResponseHead so that it contains
   either a base::PlatformFile (OS_WIN) or
   base::FileDescriptor (OS_POSIX) for passing the file
   handle from browser to renderer process.
2. Also added IPC messages for reporting download progress
   and ACK message for it. ResourceLoaderBridge::Peer::OnDownloadProgress
   is added so that the peer is notified of the download
   progress in the renderer process.
3. Load flag to kick start the resource loading for media
   files. LOAD_MEDIA_RESOURCE is added so that
   ResourceDispatcherHost knows how to use a different
   ResourceHandler for handling media resource request.
