  1. pythongh-102512: Turn _DummyThread into _MainThread after os.fork() c… 

    …alled from a foreign thread (pythonGH-113261)

Always set a _MainThread as a main thread after os.fork() is called from
a thread started not by the threading module.

A new _MainThread was already set as a new main thread after fork if
threading.current_thread() was not called for a foreign thread before fork.
Now, if it was called before fork, the implicitly created _DummyThread will
be turned into _MainThread after fork.

It fixes, in particularly, an incompatibility of _DummyThread with
the threading shutdown logic which relies on the main thread
having tstate_lock.

(cherry picked from commit 49785b0)
