[issue15806] Add context manager for the "try: ... except: pass" pattern

Hi Raymond,

This is a brilliant idea, but before it hits the streets, couldn't you possibly 
consider extending it with a kwarg to control the depth of the exception stack?

The use case I have for that are snippets like this:

    with ignored(ValueError, TypeError), ignored(ValueError, TypeError), 
ignored(ValueError, TypeError):
        a()
        b()
        c()

Or else I could write this as

    with ignored(ValueError, TypeError):
        a()

    with ignored(ValueError, TypeError):
        b()

    with ignored(ValueError, TypeError):
        c()

... but either way it looks bad. This looks a bit better to me:

    with ignored(ValueError, TypeError, depth=3):
        a()
        b()
        c()

If you deem this to be unacceptably unpythonic, then please ignore my 
suggestion.
