Issue a fatal error in case a thread is deleted which still owns resources (e.g. a binary semaphore with priority inheritance or ceiling protocol). The resource count must be checked quite late since RTEMS task variable destructors, POSIX key destructors, POSIX cleanup handler, the Newlib thread termination extension or other thread termination extensions may release resources. In this context it would be quite difficult to return an error status to the caller. An alternative would be to place threads with a non-zero resource count not on the zombie chain. Thus we have a resource leak instead of a fatal error. The terminator thread can see this error if we return an RTEMS_RESOURCE_IN_USE status for the rtems_task_delete() for example.
