[Christophe Fergeau <teuf src gnome org>]

    Add rest_proxy_auth_[un]pause
    
    They can be used in RestProxy::authenticate signals
    to suspend the current authentication attempt. This allows to get
    back to the mainloop to get the credentials, and to then rerun
    the call with the correct credentials.
