Original issue's description:
> Add new, unused methods to SpdyFramerVisitorInterface.
>
> The new methods will allow SpdyFramer to pass headers to visitors through a
> SpdyHeadersHandlerInterface.
>
> There are so many descendants of SpdyFramerVisitorInterface that I thought it
> was best to start with the interface change, and add an unused stub
> implementation everywhere.
