[PATCH 0/2] Start supporting builds with Sphinx 3.1+

[Mauro Carvalho Chehab <mchehab+huawei@kernel.org>]

Hi Jon,

This is a small patch series with just two patches.

The first one adds support at cdomain.py for two notations found on
Sphinx 3.1:

	:c:expr:
	.. c:namespace::

With that, it should now be possible to use those two C domain
tags at the media documentation, which will make it produce a
decent result with both Sphinx 1.x/2.x and Sphinx 3.1+.

The second patch manually changes the CEC documentation in
order for it to use those macros, instead of relying at the original
cdomain extensions.

I tested building the docs with both Sphinx 2.4.4 and 3.2.1.
They are identical, except by a minor difference:  the output of
:c:expr: uses a bold monospaced font with 3.1+, while it uses a
non-bold monospaced font with older versions.

Yet, the output looks decent on both versions.

I'm planning to use the same approach on all the other documents
under userspace-api/media. So, I guess it would be easier if
I could merge both the cdomain.py and the media patches via
the media tree, if this is ok for you.

With regards to patch 1, I tried first to use a hook at 'doctree-resolved',
just like the automarkup.py, but that is too late for  changing the
namespace. So, I ended hooking the extra logic at 'source-read'.

I suspect that this could be implemented on some other ways, but
this can be optimized later on, if needed.
