add join for ThreadPool without destroying the threads (#2579)
* add join for ThreadPool without destroying the threads * Make the main Thread block waiting for the worker threads to finish instead of buzy looping and do proper initialization and freeing of all variables. * Updated test to use `atomic_store` and take into account the maximum queue size of the threadpool. * - Add `ThreadPool` join function to wait for all threads to finish in the pool without destroying the threads. - Return of Thread/Mutex/CondVar `destroy()` is now "@maydiscard" and should be ignored. It will return void in 0.8.0. - Return of Mutex `unlock()` and `lock()` is now "@maydiscard" and should be ignored. They will return void in 0.8.0. - Return of ConditionVariable `signal()` `broadcast()` and `wait()` are now "@maydiscard". They will return void in 0.8.0. - Return of Thread `detatch()` is now "@maydiscard". It will return void in 0.8.0. - Buffered/UnbufferedChannel, and both ThreadPools have `@maydiscard` on a set of functions. They will retunr void in 0.8.0. - Pthread bindings correctly return Errno instead of CInt. - Return of Thread `join()` is now "@maydiscard". --------- Co-authored-by: Christoffer Lerno <christoffer@aegik.com>
