[evolution-kolab/ek-wip-porting] CamelIMAPXConnManager: virtualized get_connection() function

[Christian Hilberg <chilberg src gnome org>]

    CamelIMAPXConnManager: virtualized get_connection() function
    
    * this function is called by camel_imapx_store_get_server(),
      which in turn is called by a whole multitude of functions
      inside CamelIMAPXStore
    * in order to get our derivative server objects into the
      right places, we need to override this function in the
      derivative connection managers (or else the code dupe
      in the derivatives will become a nightmare)
