Implement referred Token Bindings

As described in when
a server sends the 'Include-Referer-Token-Binding-ID' header on a redirect
response, the client will include the TokenBindingID from the referrer in its
request to the new location in the redirect. If either connection does not
have Token Binding enabled, then this has no effect.
