Update to Chromium revision cb947c01 (#352221)

- Implement CefRequestHandler::OnBeforeBrowse using NavigationThrottle
  instead of ResourceThrottle (see http://crbug.com/537634). The CefRequest
  object passed to OnBeforeBrowse will no longer have an associated request
  identifier.
- Mac: Remove additional helper apps which are no longer required (see
  http://crbug.com/520680)
- Remove the UR_FLAG_REPORT_RAW_HEADERS flag which is no longer supported (see
  http://crbug.com/517114)
- Remove the CefBrowserSettings.java parameter. Java is an NPAPI plugin and
  NPAPI plugins are no longer supported (see http://crbug.com/470301#c11)
- Add CefFormatUrlForSecurityDisplay function in cef_parser.h
- Fix crash when passing `--disable-extensions` command-line flag (issue #1721)
- Linux: Fix NSS handler loading (issue #1727)
