Hello Guix!

With a few exceptions, our blog posts do not have a license, which is
not great as it prevents sharing and reuse, at least by those outside
Guix circles (we discussed it in the past but never got around to fixing
it).

I’d like us to clarify that, with a footer on blog posts saying that,
unless otherwise stated, posts are dual-licensed under CC-BY-SA 4.0 and
GFDL 1.3+ (the latter so we can reuse material in the cookbook and in
the manual).  Patch below.

What do people think?

If maintainers and everyone agrees, I’d like to publicly email all the
authors asking them whether they agree with the proposed licensing
terms, or whether they’d like a different free license.  The script
below enumerates blog post authors (the list needs a bit of cleanup
still):
