Rewrite how threads are spawned Instead of creating a running std::thread and returning, wait in Thread c'tor that the native thread of execution goes to sleep in idle_loop(). In this way we can simplify how search is started, because when main thread is idle we are sure also all other threads will be idle, in any case, even at thread creation and startup. After lazy smp went in, we can simpify and rewrite a lot of logic that is now no more needed. This is hopefully the final big cleanup. Tested for no regression at 5+0.1 with 3 threads: LLR: 2.95 (-2.94,2.94) [-5.00,0.00] Total: 17411 W: 3248 L: 3198 D: 10965 No functional change.
