atSaveCache, atCacheKey - derived object cache handling

atSaveCache  adds  the given busy object aso to the current derived object cache. It does this by calling
       af_savecache (manual page af_cache(3)). Prior to that, atSaveCache attaches a key attribute with the name
       __CacheKey__ to aso, by which the resulting cached object can be uniquely identified  within  the  cache.
       Return values are the same as from af_savecache (manual page af_cache(3)).

       atCacheKey  returns  an  attribute  string consisting of the attribute name __CacheKey__ and an attribute
       value built of the aso modification date, the process number and a (per process  unique)  serial  number.
       This  attribute can (and will) be used to uniquely identify attributed software objects in derived object
       caches.
