libcef: Update due to underlying chromium changes.

- External plugin loading support is now provided by webkit/glue/plugins so the libcef/plugins directory has been eliminated, with related changes.
- Modify the CefPluginInfo structure to use a more friendly data organization format.
- Remove CefUnregisterPlugin() as it is no longer functional.
- WebViewDelegate::ShowContextMenu() now receives the menu type as a bit-masked flag, so adjust the API accordingly.
- WebViewDelegate::GetContainingView() now returns a gfx::NativeViewId instead of a gfx::NativeView.
- Modify BrowserRequestContext because GetUserAgent() is now a virtual method of URLRequestContext.
- The data buffer in RequestProxy is now a net::IOBuffer.
- Add webkit_glue::GetScreenInfo().
