This is a simple script that parses the Netlink YAML spec files
(Documentation/netlink/specs/), and generates RST files to be rendered
in the Network -> Netlink Specification documentation page.

First of all, my boilerplate complaint: All extra processing for Sphinx
should really be done using Sphinx extensions instead of adding Makefile
hacks. I don't think it's sustainable to keep adding this stuff. We
chose Sphinx because it is extensible, and to avoid the Rube Goldberg
machine that the previous documentation build system was.

So I feel like we've (me included) have kind of sent Breno around in
circles on this one.  This *was* implemented as an extension once:

  https://lore.kernel.org/netdev/20231103135622.250314-1-leitao@debian.org/ (local)

At that time it seemed too complex, and I thought that an external
script would lead to a simpler implementation overall.  Perhaps I was
wrong.

I worry that a proliferation of extensions adds its own sort of
complexity and hazards - look at the things Vegard has fixed recently,
for example.  Relatively few people can work in that environment, and
extensions can make our version-support troubles worse.  So I'm not
fully sold on the idea that everything should be an extension,
especially if it can be expressed as a simple dependency and build step
in the makefile.

Some of the uglier makefile stuff we have is a different story...

Anyway, I apologize for my role in making this particular addition
harder than it needed to be.  Perhaps, for the future, we should put
together and agree on a document (of all things) on how we think this
sort of functionality should be added.

Thanks,
