VSO options across IMS restart

For all types of IMS restart except XRF takeover (cold start, warm start, emergency restart, COLDBASE, COLDCOMM and COLDSYS emergency restart), the VSO options in effect after restart are those defined to DBRC.

In the case of the XRF takeover, the VSO options in effect after the takeover are the same as those in effect for the active IMS prior to the failure that caused the XRF takeover.
