treewide: fix fallout of ip-up deprecation
See #18319 for details. Starting network-online.target manually does not
work as it hangs indefinitely.

Additionally, don't treat avahi and dhcpcd special and sync their systemd units
with the respective upstream suggestion.

27bc34f1e4 treewide: deprecate ip-up.target (#18319)
Systemd upstream provides targets for networking. This also includes a target network-online.target.

In this PR I remove / replace most occurrences since some of them were even wrong and could delay startup.

nixos/stage2: Fix mounting special filesystems
This partially reverts commit ab9537ca22.

From the manpage of systemd-nspawn(1):

  Note that systemd-nspawn will mount file systems private to the
  container to /dev, /run and similar.

Testing this in a shell turns out:

$ sudo systemd-nspawn --bind-ro=/nix/store "$(readlink "$(which ls)")" /proc
Spawning container aszlig on /home/aszlig.
Press ^] three times within 1s to kill container.
/etc/localtime does not point into /usr/share/zoneinfo/, not updating
container timezone.

Container aszlig exited successfully.

So the test on whether PID 1 exists in /proc is enough, because if we
use PID namespaces there actually _is_ a PID 1 (as shown above) and the
special file systems are already mounted. A test on the $containers
variable actually mounts them twice.

This unbreaks NixOS containers and I've tested this against the
containers-imperative NixOS test.

a6670c1a0b Fixes #18124: atomically replace /var/setuid-wrappers/ (#18186)
Before this commit updating /var/setuid-wrappers/ folder introduced
a small window where NixOS activation scripts could be terminated
and resulted into empty /var/setuid-wrappers/ folder.

That's very unfortunate because one might lose sudo binary.

Instead we use two atomic operations mv and ln (as described in
https://axialcorps.com/2013/07/03/atomically-replacing-files-and-directories/)
to achieve atomicity.

Since /var/setuid-wrappers is not a directory anymore, tmpfs mountpoints
were removed in installation scripts and in boot process.

Tested:

- upgrade /var/setuid-wrappers/ from folder to a symlink
- make sure /run/setuid-wrappers-dirs/ legacy symlink is really deleted

488f0d9cb3 systemd-unit-options: startAt can be a list
OnCalendar entrys can be specified multiple times in a systemd timer, to
make more complex scheduling possible.

Tested by manually checking the timer generated by the following:

    systemd = {
      services.huhu = {
        description = "meh";
        wantedBy = [ "default.target" ];
        serviceConfig.ExecStart = "/bin/sh -c 'printf HUHU!'";
        startAt = [ "*:*:0/30" "*:0/1:15" ];
      };
    };

It prints HUHU to the log at seconds 0, 15 and 30 of each minute.

6efcfe03ae nixos filesystems: unify early filesystems handling
A new internal config option `fileSystems.<name>.early` is added to indicate
that the filesystem needs to be loaded very early (i.e. in initrd). They are
transformed to a shell script in `system.build.earlyMountScript` with calls to
an undefined `specialMount` function, which is expected to be caller-specific.
This option is used by stage-1, stage-2 and activation script to set up and
remount those filesystems.  Options for them are updated according to systemd
defaults.

3d16af70bf nixos/stage-1: add mechanism which lustrates all impurities from / (#17784)
lustrate /ˈlʌstreɪt/ verb.
  purify by expiatory sacrifice, ceremonial washing, or some other
  ritual action.

- sudo touch /etc/NIXOS_LUSTRATE
  ⇒ on next reboot, during stage 1, everything but /nix and /boot
  is moved to /old-root
- echo "etc/passwd" | sudo tee -a /etc/NIXOS_LUSTRATE
  ⇒ on next reboot, during stage 1, everything but /nix and /boot
  is moved to /old-root; except /etc/passwd is copied back.

Useful for installing NixOS in place on another distro. For instance:

$ nix-env -iE '_: with import <nixpkgs/nixos> { configuration = {}; }; with config.system.build; [ nixos-generate-config manual.manpages ]'
$ sudo mkdir /etc/nixos
$ sudo `which nixos-generate-config`

… edit the configuration files in /etc/nixos using man configuration.nix
  if needed

  maybe add: users.extraUsers.root.initialHashedPassword = "" ?

… Build the entire NixOS system and link it to the system profile:
$ nix-env -p /nix/var/nix/profiles/system -f '<nixpkgs/nixos>' -A system --set

… If you were using a single user install:
$ sudo chown -R 0.0 /nix

… NixOS is about to take over
$ sudo touch /etc/NIXOS
$ sudo touch /etc/NIXOS_LUSTRATE

… Let's keep the configuration files we just created
$ echo etc/nixos | sudo tee -a /etc/NIXOS_LUSTRATE

$ sudo mv -v /boot /boot.bak &&
  sudo /nix/var/nix/profiles/system/bin/switch-to-configuration boot
$ sudo reboot

… NixOS boots, Stage 1 moves all the old distro stuff in /old-root.

68922e3f74 nixos/stage-1: use readlink -e in builder
The builder has this convoluted `while` loop which just replicates
`readlink -e`. I'm sure there was a reason at one point, because the
loop has been there since time immemorial. It kept getting copied
around, I suspect because nobody bothered to understand what it actually
did.

Incidentally, this fixes #17513, but I have no idea why.

etc: remove obsolete directories
This patch adds handling of a directory becoming a symlink in
/etc. Before this patch, the directory wasn't removed and then
symlinking failed, which caused directory not being updated at all.

The idea for the patch goes to @abbradar at
https://github.com/NixOS/nixpkgs/issues/16978#issuecomment-232921903:
> A heuristic idea for this -- a function `isStatic :: Path -> Bool`:
>
> * if path `/etc/foo` is a file, return True iff it's a symlink to `/etc/static/foo`.
> * if path is a directory, return True iff for all items in it `isStatic` is True.
>
> On any conflicts, if old path is static, it's safe to replace and/or
> delete stale. Otherwise make a backup and notify the user via a
> journal entry and console output.

The only difference here -- it will not replace user configs.

This also fixes https://github.com/NixOS/nixpkgs/issues/16978.
