fb22e438b2 scripts: sphinx-pre-install: move get_system_release()
The code at get_system_release() is actually a helper function,
independent from the actual Sphinx verification checker. Move
it to MissingCheckers class, where other checkers are present.

With that, the entire distro-specific handler logic, with
all its complexity is confined at SphinxDependencyChecker
class.

1ad72e9dfa scripts: sphinx-pre-install: move package instructions to a new func
Currently, if Python < 3.7, package install will fail. That happens
with OpenSuse Leap and RHEL-based ver 8 distros.

OpenSuse allows installing Sphinx with Python 3.11, but RHEL-based
distros don't.

the recomendation on a new function that will check for a
paramtere to be called.

1a7da749f1 scripts: sphinx-pre-install: improve Gentoo package deps logic
It took me a lot of time, but I guess understand now what it
takes to install a package on Gentoo.

Handling dependencies is a nightmare, as Gentoo refuses to emerge
some packages if there's no package.use file describing them.
To make it worse, compilation flags shall also be present there
for some packages. If USE is not perfect, error/warning messages
like those are shown:

  gnome-base/librsvg dev-texlive/texlive-xetex media-fonts/dejavu dev-python/pyyaml

...

!!! The following binary packages have been ignored due to non matching USE:

    =media-gfx/graphviz-12.2.1-r1 X pdf -python_single_target_python3_13 qt6 svg
    =media-gfx/graphviz-12.2.1-r1 X pdf python_single_target_python3_12 -python_single_target_python3_13 qt6 svg
    =media-gfx/graphviz-12.2.1-r1 X pdf qt6 svg
    =media-gfx/graphviz-12.2.1-r1 X pdf -python_single_target_python3_10 qt6 svg
    =media-gfx/graphviz-12.2.1-r1 X pdf -python_single_target_python3_10 python_single_target_python3_12 -python_single_target_python3_13 qt6 svg
    =media-fonts/noto-cjk-20190416 X
    =app-text/texlive-core-2024-r1 X cjk -xetex
    =app-text/texlive-core-2024-r1 X -xetex
    =app-text/texlive-core-2024-r1 -xetex
    =dev-libs/zziplib-0.13.79-r1 sdl

If emerge is allowed, it will simply ignore the above packages,
creating an incomplete installation, which will later fail when
one tries to build docs with images or build PDFs.

After the fix, command line commands to produce the needed USE
chain will be emitted, if they don't exist yet.

        sudo su -c 'echo "media-gfx/graphviz" > /etc/portage/package.use/graphviz'
        sudo su -c 'echo "media-gfx/imagemagick" > /etc/portage/package.use/imagemagick'
        sudo su -c 'echo "media-libs/harfbuzz icu" > /etc/portage/package.use/media-libs'
        sudo su -c 'echo "media-fonts/noto-cjk" > /etc/portage/package.use/media-fonts'
        sudo su -c 'echo "app-text/texlive-core xetex" > /etc/portage/package.use/texlive'
        sudo su -c 'echo "dev-libs/zziplib sdl" > /etc/portage/package.use/zziblib'

The new logic tries to be smart enough to detect for missing files
and missing arguments. Yet, as Gentoo seems to require users to
manage those package.use files by hand, the logic isn't perfect:
users may still need to verify for conflicts on different use
files.

cccc538981 scripts: sphinx-pre-install: add a missing f-string marker
I forgot one f-string marker, with turned to be affecting 3
lines, because of cut-and-paste ;-)

Use the proper f-string marker to print Sphinx version at
the hint lines. Yet, we don't want to print as a tuple, so
call ver_str() for it.

Ideally, we would be placing it directly at the f-string, but
Python 3.6 f-string support was pretty much limited. Only
3.12 (PEP 701) makes it similar to Perl, allowing expressions
inside it. It sounds that function call itself was introduced
on 3.7.

As we explicitly want this one to run on 3.6, as latest Leap
comes with it, we can't use function calls on f-string.

2cb4877b74 scripts: sphinx-pre-install: Address issues with OpenSUSE Leap 15.x

Suggest the newer version:

        You should run:

                sudo zypper install --no-recommends ImageMagick graphviz python311-pyyaml

        Sphinx needs to be installed either:
        1) via pip/pypi with:

           Currently not possible.

           Please upgrade Python to a newer version and run this script again

        2) As a package with:

                sudo zypper install --no-recommends python311-Sphinx

            Please note that Sphinx >= 3.0 will currently produce false-positive
           warning when the same name is used for more than one type (functions,
           structs, enums,...). This is known Sphinx bug. For more details, see:
