[issue41150] pipes uses text files and the locale encodig

[Serhiy Storchaka]

New submission from Serhiy Storchaka <storchaka+cpython at gmail.com>:

The pipes module was designed as a Python interface to Unix shell pipelines. In Python 2 it works with binary streams (on Unix). But in Python 3 it opens all files and pipes in text mode with the locale encoding. It makes it unapplicable for processing binary data and text data non-encodable with the locale encoding.
