[New-bugs-announce] [issue18373] implement sys.get/setbyteswarningflag()

[Daniel Holth]

New submission from Daniel Holth:

This patch lets the user get/set the byteswarningflag() to control whether warnings are emitted at runtime (pursuant to the configuration of the warnings module, of course).

The idea is that a user who is concerned with interacting with bytes correctly would use a context manager to set str(bytes) to raise exceptions during a critical serialization.

TODO the hypothetical context manager would also have to push/pop the warnings state to work correctly. Maybe str(bytes) can raise a regular exception if byteswarningflag() is high enough?

TODO don't know if this plays nicely when there are no threads
