Issue 39883: Use BSD0 license for code in docs

Currently using code examples and recipes from the documentation is complicated by the fact that they are all under the Python 2.0 license.  Putting them under a more permissive license, particular the BSD0 license, would make them much easier to use in other projects.

What is the complication?  The Python license is already rather permissive.  Anyway, there is a name@mail.python.org address for trademark issues, listed on the site, and it might be appropriate for license legal questions also.  Or this might be a question for discuss.python.org.

Hi Terry,

Please take a look at the linked PR.  This was already discussed on the python-ideas mailing list and Guido agreed this is a good idea.  It is currently waiting on a PSF board decision.  Guido requested I create a blurb, and that required a corresponding issue number, so I created this issue.  

But to answer your question, the problem is incorporating code into an existing project.  The whole point of examples and recipes is that they be used in other projects.  But keeping them under the Python 2.0 license makes this hard, since it requires all the documentation keep that same license.  So you can't use, say, an itertools recipe without keeping a separate license for that code, and some way to identify which code falls under that license.

OK.  I looked at the PR.  Normally, issue comes first, with justification and approval status.

FWIW the PSF board approved the change.

Todd, you have a PR for the pydotorg repo as well, right? Can you link it here?

It doesn't seem to went let me add it to linked pull requests.
