replace context::terminated_is_linked() by context::is_terminated()
...
- context::terminated_is_linked() might be missleading because this
state is transient
- if the context is pushed to the terminated-queue,
context::terminated_is_linked() returns true, if the context is
removed from terminated-queue context::terminated_is_linked() returns
false
- new flag flag_terminated intoduced
- flag_terminated will be set in context::set_terminated_(), which will
be called for worker context' in the lambda
