reorder member variables of context

the member variables of context are allocated

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

Make awakened() unconditionally insert fiber.
...
There was a bug when the ready queue wasn't empty, but there was no
lower-priority fiber already in the queue. In that case the fiber wouldn't be
inserted. We want the loop just to advance the iterator, but to perform the
insert regardless of where the iterator ends up. (With this logic, empty() is
no longer a special case.)
Restore the ~Verbose() message.
