Addresses Issue #10838 : The subprocess now module includes
...
SubprocessError and TimeoutError in its list of exported names for the
users wild enough to use "from subprocess import *".
MAXFD, mswindows and list2cmdline should be dealt with (renamed or
moved) in separate commits.
Committed at 35,000ft. Thanks chromebook free gogo wifi passes!

the Visual Studio solution and removes any references to the w9xpopen

Fixes Issue #16114 : The subprocess module no longer provides a

misleading error message stating that args[0] did not exist when

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.
