Spats Functional change to STPDRV and STPBRE

To reduce TCB SRB swaps we now statically link STPNAT to the Natural nucleus, meaning the natural version release is tied to the Adabas version release, and vice versa.

I have been told this functionality is used in other pieces of code. " there are many SAG owned modules called from NAT that they recognize and stay in SRB mode." Can this code exempt since it is a SAG owned module, in which case we could explore dynamic loading again?
