7a794647ae 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

00ae711cd7 join only non-terminated fibers 
- context::join() adds active-context to wait-queue only
  if joined context is not terminated
- we can not use terminated_is_linked() because the context
  might already be removed from scheudler's termianted-queue

dd0e1d1893 add autoreset_event for waling up dispatcher context 
- dispatcher waits on autoreset_event if ready-queue is empty
- autoreset_event is set if a ready context is pushed to the
  ready-queue

8c4dda107c support signaling a fiber from another thread 
- for this first version lockfree::queue<> is used
- maybe Dimitry Byukov's mpsc intrusive queue is better suited

51d08226a4 if not fibers in queues - suspend till signaled or timeout 
- if no fibers are ready to run suspend the thread and wait till
  * signaled by scheduler::signal() for new fiber (ready to run)
  * time_point of a sleeping fiber has reached

7233f617d7 remove class scheduler - fiber_context has static TLS 
- detail:.scheduler was removed
- fiber_context has a static thread-local pointer to the active
  fiber_context
- fiber_context has member to pointer of fiber_manager
- functions of fiber_manager are accessed only via fiber_context
- if fiber f is resumed, the fiber_manager of the current active fiber
  f' is assigned to f
  -> that is necessary if f was stolen form another thread
