Implement a chromoting client using X11

Using XRender to render the chromoting client. This patch has done several things:
1. Rename chromotocol_pb to remoting
2. Defined ChromotingView as the display area of the remote view
3. Implemented X11Client as the client that uses X11 for display
4. Implemented X11View that uses XRender for drawing
5. Fixed several problems in host capturer and encoder
