MXS-2196: Split session startup into two parts

Browse Source 
The session allocation now has two distinct parts: the initialization of
the session itself and the creation of the router and filter
sessions. This allows sessions to be allocated the moment a client DCB is
created instead of only after the authentication is complete. With this
change, the need for the dummy session is removed.
