c3e270f4ee docs: add a "front matter" snippet to our markdown pages
It turns out Jekyll (the engine behind GitHub Pages) requires that pages
include a "Front Matter" snippet of YAML at the top for proper rendering.

Omitting it will still render the pages, but including it opens up new
possibilities, such as using a {% for %} loop to generate index.md instead of
requiring a separate script.

I'm hoping this will also fix the issue with some of the pages (notably
CODE_OF_CONDUCT.html) not being available under systemd.io

Tested locally by rendering the website with Jekyll. Before this change, the
*.md files were kept unchanged (so not sure how that even works?!), after this
commit, proper *.html files were generated from it.

06da5c63dd meson: make net.naming-scheme= default configurable
This is useful for distributions, where the stability of interface names should
be preseved after an upgrade of systemd. So when some specific release of the
distro is made available, systemd defaults to the latest & greatest naming
scheme, and subsequent updates set the same default. This default may still
be overriden through the kernel and env var options.

A special value "latest" is also allowed. Without a specific name, it is harder
to verride from meson. In case of 'combo' options, meson reads the default
during the initial configuration, and "remembers" this choice. When systemd is
updated, old build/ directories could keep the old default, which would be
annoying. Hence, "latest" is introduced to make it explicit, yet follow the
upstream. This is actually useful for the user too, because it may be used
as an override, without having to actually specify a version.

f7e81fd96f udev: introduce udev net_id "naming schemes"
With this we can stabilize how naming works for network interfaces. A
user can request through a kernel cmdline option or an env var which
scheme to follow. The idea is that installers use this to set into stone
(a very soft stone though) the scheme used during installation so that
interface naming doesn't change afterwards anymore.

Why use env vars and kernel cmdline options, and not a config file of
its own?

Well, first of all there's no obvious existing one to use. But more
importantly: I have the feeling that this logic is kind of an incomplete
hack, and I simply don't want to do advertise this as a perfectly
working solution. So far we used env vars for the non-so-official
options and proper config files for the official stuff. Given how
incomplete this logic is (i.e. the big variable for naming remains the
kernel, which might expose sysfs attributes in newer versions that we
check for and didn't exist in older versions — and other problems like
this), I am simply not confident in giving this first-class exposure in
a primary configuration file.

33eb44fe4a sulogin-shell: Use force if SYSTEMD_SULOGIN_FORCE set
When the root account is locked sulogin will either inform you of
this and not allow you in or if --force is used it will hand
you passwordless root (if using a recent enough version of util-linux).

Not being allowed a shell is ofcourse inconvenient, but at the same
time handing out passwordless root unconditionally is probably not
a good idea everywhere.

This patch thus allows to control which behaviour you want by
setting the SYSTEMD_SULOGIN_FORCE environment variable to true
or false to control the behaviour, eg. via adding this to
'systemctl edit rescue.service' (or emergency.service):

[Service]
Environment=SYSTEMD_SULOGIN_FORCE=1

Distributions who used locked root accounts and want the passwordless
behaviour could thus simply drop in the override file in
/etc/systemd/system/rescue.service.d/override.conf

8cbb7d8783 efi: allow ESP validity checks to be turned off
let's add an env var for this, as this really shouldn't be a top-level
feature, as it turning off the validity checks certainly isn't
advisable.

9e825ebf4f docs: move doc/ to docs/
The docs/ directory is special in GitHub, since it can be used to serve GitHub
Pages from, so there's a benefit to switching to it in order to expose it
directly as a website.

Updated references to it from the documentations themselves, from the
CONTRIBUTING.md file and from Meson build files.
