[docs] [issue14379] Several traceback docs improvements

[anatoly techtonik]

New submission from anatoly techtonik <techtonik at gmail.com>:

Some notes about current `traceback` documentation:
http://docs.python.org/library/traceback.html

1. It needs a mentioning that traceback module works with traceback objects and frame objects

2. Functions that work with frames should probably be grouped together

3. Docs for frame function should include info about where to get frames (e.g. 
http://docs.python.org/library/inspect.html#the-interpreter-stack)

4. There is no traceback object description, which should be at http://docs.python.org/library/sys.html#sys.exc_info
