Create Authentication Plugins

Provides the framework for creating authentication plugins and using
them from a session object.

To allow this system to co-exist with the original client there is a bit
of a hack. The client object itself is now also an authentication
plugin, that supports the original client pattern. If a client is
created without a session object then that session object uses the
client as it's authentication plugin.
