[issue4036] Support bytes for subprocess.Popen()

[STINNER Victor]

New submission from STINNER Victor <victor.stinner at haypocalc.com>:

subprocess doesn't support bytes for the "args" argument.
 - On Windows, subprocess._execute_child() converts args to a string 
if it was a list
 - On UNIX, subprocess._execute_child() converts args to a list if 
it's a string

If shell=True, _execute_child() adds a prefix to the arguments.

I don't know if subprocess should accept bytes in a command line. 
Attached patch fixes POSIX version of subprocess to support bytes.
