[issue15805] Add stdout redirection tool to contextlib

[Raymond Hettinger]

Raymond Hettinger added the comment:

I like Nick's proposed variant and think it should go in contextlib, not the mocking library.  Redirection has a lot of use cases that has nothing to do with mocking-up test suites.  Contextlib is about general purpose context-managers that apply in many situations (the closing() context manager is a good example).
