Validation enhancements

HCD implements several new validation checks to help users to avoid unintended results:

New warning message when a CF CIB connection changes due to connectivity updates

HCD issues a new warning message CBDG422I, when users add or delete a CSS to/from a CIB CHPID that involves a change of the coupling facility connection, affecting the definition of the connected processor. This message informs the user about the change and a potentially required dynamic activation of the target processor.

Warning message CBDA845I now also issued for ACTIVATE SOFT system command

For users of the HCD Activate ... dialogs, if required, HCD issues warning message CBDA845I when users specify an ACTIVATE software-only request without hardware validation, because this will not process involved changes to coupling facility control units and devices for the software. This message is now also issued, if users specify an ACTIVATE SOFT system command without hardware validation.
