Merge branch 'mauro' into docs-mw

Mauro's work to include documentation from our Python modules. His cover
letter follows:

This is an extended version of:
https://lore.kernel.org/linux-doc/cover.1768488832.git.mchehab+huawei@kernel.org/

It basically adds everything we currently have inside libs/tool/python
to "tools" book inside documentation.

This version should be independent of the other series yet to be merged,
(including the jobserver one).

The vast amount of changes here are docstring cleanups and additions.
They mainly consists on:

- ensuring that every phrase will end with a period, making it uniform
along all files;
- cleaning ups to better uniform docstrings;
- variable descriptions now use "#:" markup, as it allows autodoc to
add them inside the documentation;
- added some missing docstrings;
- some new blank lines at comments to make ReST syntax parser happy;
- add a couple of sphinx markups (mainly, code blocks).

Most of those are minor changes, affecting only comments.

It also has one patch per libarary type, adding them to docs.

For kernel-doc, I did the cleanups first, as there is one code block
inside tools/lib/python/kdoc/latex_fonts.py that would cause a Sphinx
crash without such markups.

The series actually starts with 3 fixes:

- avoid "*" markups on indexes with deep> 3 to override text
- a variable rename to stop abusing doctree name
- don't rely on cwd to get Documentation/ location

patch 4 adds support to document scripts either at:
- tools/
- scripts/

patch 5 contains a CSS to better display autodoc html output.

For those who want to play with documentation, documenting a python
file is very simple. All it takes is to use:

.. automodule:: lib.python.<dir+name>

Usually, we add a couple of control members to it to adjust
the desired documentation scope (add/remove members, showing class
inheritance, showing members that currently don't have
docstrings, etc). That's why we're using:

.. automodule:: lib.python.kdoc.enrich_formatter
:members:
:show-inheritance:
:undoc-members:

(and similar) inside tools/kdoc*.rst.

autodoc allows filtering in/out members, file docstrings, etc.

It also allows documenting just some members or functions with
directives like:

..autofunction:
..automember:

Sphinx also has a helper script to generate .rst files with
documentation:

$ sphinx-apidoc -o foobar tools/lib/python/

which can be helpful to discover what should be documented,
although changes are needed to use what it produces.

docs: kdoc: fix logic to handle unissued warnings

Changeset 469c1c9eb6c9 ("kernel-doc: Issue warnings that were silently discarded")
didn't properly addressed the missing messages behavior, as
it was calling directly python logger low-level function,
instead of using the expected method to emit warnings.

Basically, there are two methods to log messages:

- self.config.log.warning() - This is the raw level to emit a
warning. It just writes the a message at stderr, via python
logging, as it is initialized as:

self.config.log = logging.getLogger("kernel-doc")

- self.config.warning() - This is where we actually consider a
message as a warning, properly incrementing error count.

Due to that, several parsing error messages are internally considered
as success, causing -Werror to not work on such messages.

While here, ensure that the last ignored entry will also be handled
by adding an extra check at the end of the parse handler.

kernel-doc: add support for handling global variables

Specially on kAPI, sometimes it is desirable to be able to
describe global variables that are part of kAPI.

Documenting vars with Sphinx is simple, as we don't need
to parse a data struct. All we need is the variable
declaration and use native C domain ::c:var: to format it
for us.

Add support for it.
