Since all object handler contains exactly the same CASE statement for STEP definition, I would recommend that each object handler simply returns the STEP he belongs to.
This fix should "simply" issue #2499.
* mark inactive objects in repo list
Inactive object are marked in the repo list
The sort order for changed files is not changed
unchanged inactive files come right after the changed files
* move acitve check to object interface
* add is_active for objects up to F
* add is_active for objects up to P
* add is_active for objects up to T
* add is_active for objects up to X
all core object implement (except SSFO) the standard active check via FM RS_INACTIVE_OBJECTS_WARNING now
* add is_active to plugins bridge - always active
* finish object interface implementation + objects
* add is_active for offline with object interface
* rename returning to RV_
* use returning for serialize
* cleanup, PP, UT
