gh-155334: Add start parameter to threading.Thread

[vstinner]

Use start=True in the stdlib.

• Issue: threading.Thread: Add start=False parameter to start immediately the thread #155334

[vstinner]

I wasn't sure about changing the introduction example of threading documentation: https://docs.python.org/dev/library/threading.html#introduction

Should it be updated to use start=True?

...
# Start threads for each linkthreads= []
forlinkinlinks:
# Using `args` to pass positional arguments and `kwargs` for keyword argumentst=threading.Thread(target=crawl, args=(link,), kwargs={"delay": 2}, start=True)
threads.append(t)
# Wait for all threads to finishfortinthreads:
t.join()

I didn't add the start parameter to the threading.Timer subclass of threading.Thread. It can be added later if start is widely adopted.
