445ad997ab Fix #14470. Remove w9xpopen per PEP 11. 
As stated in PEP 11, 3.4 removes code on Windows platforms where
COMSPEC points to command.com. The w9xpopen project in Visual Studio
was added to support that case, and there was a special case in subprocess
to cover that situation. This change removes the w9xpopen project from
the Visual Studio solution and removes any references to the w9xpopen
executable.

c2c4cb624b Fixes issue #16140: The subprocess module no longer double closes its 
child subprocess.PIPE parent file descriptors on child error prior to
exec().

This would lead to race conditions in multithreaded programs where
another thread opened a file reusing the fd which was then closed out
from beneath it by the errant second close.

d4b645ef42 Remove the subprocess "bad exception data" warning (formerly a print!) 
all together and just include the repr of the data in the exception
itself instead of the useless string "Unknown".

This code path is unlikely to even be possible to take given the
nature of the pipe it gets subprocess data from.

a10ddb8a55 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.

5591b02a4c 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.

zombis) and close pipes.

(this was broken due to the 2.x to 3.x transition; communicate() support
is still sketchy)
