bpo-37266: Daemon threads are now denied in subinterpreters by vstinner · Pull Request #14049

In a subinterpreter, spawning a daemon thread now raises an
exception. Daemon threads were never supported in subinterpreters.
Previously, the subinterpreter finalization crashed with a Pyton
fatal error if a daemon thread was still running.

* Add _thread._is_main_interpreter()
* threading.Thread.start() now raises RuntimeError if the thread is a
  daemon thread and the method is called from a subinterpreter.
* The _thread module now uses Argument Clinic the new function.
* Use textwrap.dedent() in test_threading.SubinterpThreadingTests

* use print() using flush=True
* make the read end of the pipe non-blocking to avoid hanging forever
