- fix a bug in CopyHandler (while copying slot objects) - found and fixed two cases, where xotcl could crash during deletion of active objects - simplified deletion logic of active objects significantly unsing an explicit activation count - removed old deletion logic (state variable callIsDestroy, callstate XOTCL_CSC_CALL_IS_DESTROY, destroyedCmd on stack content) - removed now obsolete functions CallStackMarkDestroyed() and CallStackMarkUndestroyed() - made changes for with and without TCL85STACK
- removed XOTclCallStack definition and datastructures, when compiled with TCL85STACK - CallStackPop(): when compiled with TCL85STACK, the function just initializes a given call stack content; allocation based on C-Stack
