The sphinx-pre-install supports installing sphinx via a virtual
environment using pip/pypi or directly from the distribution's
package, when --no-virtualenv is used.
However, even when --no-virtualenv, the current logic is
still recomending to install a virtual env, due to a regression.
It turns that the logic there is complex, as it depends on
several different conditions.
Split the code which recommends Sphinx on two separate
functions, in order to clean up the code.

sphinx-pre-install is picky when it comes to parsing sphinx versions; it
failed when run with sphinx 4.0.0b1. Tweak the regex to tolerate a
trailing "bN" on the version number.

The kernel build system as a whole is dropping support for Python 2, so we
should do the same. The effects are rather small, especially considering
that much of the deleted code was not doing anything under any version of
Python anyway.

Change every shebang which does not need an argument to use /usr/bin/env.
This is needed as not every distro has everything under /usr/bin,
sometimes not even bash.

The sphinx-pre-install script will put out a verbose message recommending
an upgrade for anybody running less than 2.4.4 - which was only released in
March. So *everybody* will see that warning at this point. Let's only
warn if the user is below our generally recommended version (1.7.9
currently).
It might be good to put out a warning if people are explicitly making PDF
files, but would need to be done in a different place and relatively few
people do that.

When the script detects the need for an upgrade, it will
print either a warning or a note.
Let's change a little bit the order where messages will be
displayed, in order to make easier for the user to identify
the more important messages.
It should now be like this:
Detected OS: Fedora release 31 (Thirty One).
Sphinx version: 1.7.9
Note: It is recommended at least Sphinx version 2.4.4 if you need PDF support.
To upgrade Sphinx, use:
/usr/bin/python3 -m venv sphinx_2.4.4
. sphinx_2.4.4/bin/activate
pip install -r ./Documentation/sphinx/requirements.txt
If you want to exit the virtualenv, you can use:
deactivate
All optional dependencies are met.
Needed package dependencies are met.

When python3 creates a venv, it adds python into it!
This causes any upgrade recommendation to look like this:
/devel/v4l/docs/sphinx_1.7.9/bin/python3 -m venv sphinx_2.4.4
. sphinx_2.4.4/bin/activate
pip install -r ./Documentation/sphinx/requirements.txt
With is wrong (and it may not work). So, when recomending
an upgrade, exclude the venv dir from the search path, and
get the system's python.

As requested by Jon, change the version check, in order to not
emit a warning if version is >= 1.7.9, but below 2.4.4.
After this patch, if someone used an older version, it will
say:
./scripts/sphinx-pre-install
Sphinx version 1.7.9
Note: It is recommended at least Sphinx version 2.4.4 if you need PDF support.
Detected OS: Fedora release 31 (Thirty One).
To upgrade Sphinx, use:

The Arch-linux detection is hit by catting /etc/issue, whose
contents is (nowadays):
Arch Linux \r (\l)
It sounds a little ackward to print such string, so,
instead, let's use the /etc/os-release file, with exists
on lots of distributions and should provide a more reliable
result.
We'll keep the old tests before it, in order to avoid possible
regressions with the other distros, although the new way should
probably work on all the currently supported distributions.

With Ubuntu 16.04 (and presumably Debian distros of the same age),
the instructions for setting up a python virtual environment should
do so with the python 3 interpreter. On these older distros, the
default python (and virtualenv command) might be python2 based.
Some of the packages that sphinx relies on are now only available
for python3. If you don't specify the python3 interpreter for
the virtualenv, you get errors when doing the pip installs for
various packages
Fix this by adding '-p python3' to the virtualenv recommendation
line.

When using a non-release version of Sphinx, from a local build (with
improvements for kernel doc handling, why not),
sphinx-build --version
reports versions of the form
sphinx-build 3.0.0+/4703d9119972
i.e. base version, a plus symbol, slash, and the start of the git hash
of whatever repository the command is run in (no, not the hash that
was used to build Sphinx!).
This patch fixes the installation check in sphinx-pre-install to
recognise such version output.
