[issue8603] Create a bytes version of os.environ and getenvb()

[STINNER Victor]

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

As discussed in issue #8514, I propose a bytes version of os.envionb which would be synchronized with os.environ (which is possible thanks to surrogateescape error handler).

I also propose a os.getenvb()->bytes function.

I don't know yet if it's a good idea of not, but my patch accepts both bytes and str for os.environ(b).get() and os.getenv(b)().

antoine> In posixmodule.c, (...) if memory allocation of the bytes
antoine> object fails, we should error out.

I would require to change also the Windows version and the code specific to OS/2. Ok to do that, but after closing this issue ;-) I don't want to change to much things at the same time.
