Issue #23694 : Fix usage of _Py_open() in the _posixsubprocess module
...
Don't call _Py_open() from _close_open_fds_safe() because it is call just after
fork(). It's not good to play with locks (the GIL) between fork() and exec().
Use instead _Py_open_noraise() which doesn't touch to the GIL.

Issue #23694 : Enhance _Py_open(), it now raises exceptions
...
* _Py_open() now raises exceptions on error. If open() fails, it raises an
OSError with the filename.
* _Py_open() now releases the GIL while calling open()
* Add _Py_open_noraise() when _Py_open() cannot be used because the GIL is not
held

Issue #22290 : Fix error handling in the _posixsubprocess module.

* Don't call the garbage collector with an exception set: it causes an
assertion to fail in debug mode.
* Enhance also error handling if allocating an array for the executable list
failed.
* Add an unit test for 4 different errors in the _posixsubprocess module.

Don't restrict ourselves to a "max" fd when closing fds before exec()
...
when we have a way to get an actual list of all open fds from the OS.
Fixes issue #21618 : The subprocess module would ignore fds that were
inherited by the calling process and already higher than POSIX resource
limits would otherwise allow. On systems with a functioning /proc/self/fd
or /dev/fd interface the max is now ignored and all fds are closed.

Fixes Issue #16114 : The subprocess module no longer provides a
...
misleading error message stating that args[0] did not exist when
either the cwd or executable keyword arguments specified a path that
did not exist.
It now keeps track of if the child got as far as preexec and reports it if
not back to the parent via a special "noexec" error message value in
the error pipe so that the cwd can be blamed for a failed chdir
instead of the exec of the executable being blamed instead.
The executable is also always reported accurately when exec fails.
Unittests enhanced to cover these cases.

* Replaces the internals of the subprocess module from fork through exec on

POSIX systems with a C extension module. This is required in order for

available.
The unittest executes tests on both code paths to guarantee compatibility.
* Moves PyLong_FromPid and PyLong_AsPid from posixmodule.c into longobject.h.
