Fixed method names in exception messages 
These methods are not !-suffixed, and the messages were very
confusing.

Wake up join list within thread EC context. (#4471) 
* Wake up join list within thread EC context.

* Consume items from join list so that they are not re-executed.

If `rb_fiber_scheduler_unblock` raises an exception, it can result in a
segfault if `rb_threadptr_join_list_wakeup` is not within a valid EC. This
change moves `rb_threadptr_join_list_wakeup` into the thread's top level EC
which initially caused an infinite loop because on exception will retry. We
explicitly remove items from the thread's join list to avoid this situation.

* Verify the required scheduler interface.

* Test several scheduler hooks methods with broken `unblock` implementation.

Expose scheduler as public interface & bug fixes. (#3945) 
* Rename `rb_scheduler` to `rb_fiber_scheduler`.

* Use public interface if available.

* Use `rb_check_funcall` where possible.

* Don't use `unblock` unless the fiber was non-blocking.

Benoit Daloze 738a089b3a Rename scheduler.{mutex_lock,mutex_unlock} to {block,unblock} 
* Move #kernel_sleep next to #block as it is similar
 2020-09-17 14:30:40 +02:00
Benoit Daloze 178c1b0922 Make Mutex per-Fiber instead of per-Thread 
* Enables Mutex to be used as synchronization between multiple Fibers
  of the same Thread.
* With a Fiber scheduler we can yield to another Fiber on contended
  Mutex#lock instead of blocking the entire thread.
* This also makes the behavior of Mutex consistent across CRuby, JRuby and TruffleRuby.
* [Feature #16792]
