This patchset brings a number of improvements:

 - Allow a tiemout that is different from the default 60s for
   pending authentication. 60s is a bit tight, especially when
   being redirected to a complicated web login process.
 - Make the server side auth-pending support no longer
   dependent on management interface but also allow scripts
   and plugins to utilise it.
 - Introduce deffered authentication support for scripts.
   Deferred authentication is a necessary requirement for
   pending authentication.

The branch is also available here: https://github.com/schwabe/openvpn/tree/schwabe/auth_pending
