596e447076 Reintroduce ExitType
This introduces `ExitType=main|cgroup` for services.
Similar to how `Type` specifies the launch of a service, `ExitType` is
concerned with how systemd determines that a service exited.

- If set to `main` (the current behavior), the service manager will consider
  the unit stopped when the main process exits.

- The `cgroup` exit type is meant for applications whose forking model is not
  known ahead of time and which might not have a specific main process.
  The service will stay running as long as at least one process in the cgroup
  is running. This is intended for transient or automatically generated
  services, such as graphical applications inside of a desktop environment.

Motivation for this is #16805. The original PR (#18782) was reverted (#20073)
after realizing that the exit status of "the last process in the cgroup" can't
reliably be known (#19385)

This version instead uses the main process exit status if there is one and just
listens to the cgroup empty event otherwise.

The advantages of a service with `ExitType=cgroup` over scopes are:
- Integrated logging / stdout redirection
- Avoids the race / synchronisation issue between launch and scope creation
- More extensive use of drop-ins and thus distro-level configuration:
  by moving from scopes to services we can have drop ins that will affect
  properties that can only be set during service creation,
  like `OOMPolicy` and security-related properties
- It makes systemd-xdg-autostart-generator usable by fixing [1], as obviously
  only services can be used in the generator, not scopes.

9214f2999b CODING_STYLE: allow joined variable declarations and function calls
… but only for a single variable.

The guidelines already allowed declaring variables at the point of
initialization. But not making a function call to do that. Let's allow that
now.  The existing style of declaring and initializing seperate is still
allowed, and whatever makes most sense should be used.

4c2ee5c7f2 homework: allow specifying explicit additional mount options when using CIFS backend

bf15879b39 homework: allow specifying a dir component in CIFS services
Allow specifying CIFS services in the format //host/service/subdir/… to
allow multiple homedirs on the same share, and not in the main dir of
the share.

All other backends allow placing the data store at arbitrary places,
let's allow this too for the CIFS backend. This is particularly useful
for testing.

4a4654e024 nspawn: add --suppress-sync=yes mode for turning sync() and friends into NOPs via seccomp
This is supposed to be used by package/image builders such as mkosi to
speed up building, since it allows us to suppress sync() inside a
container.

This does what Debian's eatmydata tool does, but for a container, and
via seccomp (instead of LD_PRELOAD).

bcce9a609a docs: mark spdx headers with the default license to website files
Those were added in b41a3f66c9 without

already got a header previously, so this only touches the remaining.

The same should be done for docs/_data/extra_pages.json, but it's json, and
json doesn't allow comments.

d55ad7fe96 mkosi: move distro files to mkosi.default.d/
With this change, "mkosi build" will automatically build systemd for the
current distro without any further configuration. If people want to do a
cross-distro build by default, they can still create mkosi.default, but I
assume that this is relatively rare.

If people have symlinked mkosi.default to one of the files in .mkosi/, they'll
need to adjust the symlink.

(Building without configuration would always fail, since systemd has many many
required dependencies. I think it's nicer to do the most commonly expected
thing by default, i.e. rebuild for the current distro.)

Mkosi is nowadays packaged for most distros, so recommend installing of distro
packages as the primary installation mechanism.

8859b8f77a Mount encrypted swap partitions via gpt-auto
If the auto-discovered swap partition is LUKS encrypted, decrypt it
automatically.

This aligns with the Discoverable Partitions Specification, though I've
also updated it to explicitly mention that LUKS is now supported here.

Since systemd retries any key already in the kernel keyring, if the swap
partition has the same passphrase as the root partition, the user won't
be prompted a second time for a second passphrase.

This reverts commit cb0e818f7c.

After this was merged, some design and implementation issues were discovered,
see the discussion in #18782 and #19385. They certainly can be fixed, but so
far nobody has stepped up, and we're nearing a release. Hopefully, this feature
can be merged again after a rework.

Fixes #19345.

data, and use it when authenticating with it.

This also adds explicit "uv" support: we'll only allow it to happen when
the client explicity said it's OK. This is then used by clients to print
a nice message suggesting "uv" has to take place before retrying
allowing it this time. This is modelled after the existing handling for
"up".
