Subject: [PATCH] Conn_SyncServerStruct(): test all connections; and work case
 insensitive

Fix synchronization of established connections and configured server
structures after a configuration update:

 - Not only test servers that already have a connection, but also check
   and update configured servers to which a new connection is beeing
   established (SERVER_WAIT state).

 - And do the server name comparision case-insensitive.
