nixos/stage-2-init: Clean up legacy commands
We can perform most of the mkdir/ln/rm using systemd-tmpfiles
instead which cleans up the script.

/bin and /home are created by their activation script snippets

usbfs is deprecated and unused.

hwclock seems to be automatically executed by systemd on startup.

The mkswap to prevent hibernation cycles seems to be executed by systemd
as well since the provided regression tests succeeds.

4a9d9928dc nixos/nix-daemon: use structural settings
The `nix.*` options, apart from options for setting up the
daemon itself, currently provide a lot of setting mappings
for the Nix daemon configuration. The scope of the mapping yields
convience, but the line where an option is considered essential
is blurry. For instance, the `extra-sandbox-paths` mapping is
provided without its primary consumer, and the corresponding
`sandbox-paths` option is also not mapped.

The current system increases the maintenance burden as maintainers have to
closely follow upstream changes. In this case, there are two state versions
of Nix which have to be maintained collectively, with different options
avaliable.

This commit aims to following the standard outlined in RFC 42[1] to
implement a structural setting pattern. The Nix configuration is encoded
at its core as key-value pairs which maps nicely to attribute sets, making
it feasible to express in the Nix language itself. Some existing options are
kept such as `buildMachines` and `registry` which present a simplified interface
to managing the respective settings. The interface is exposed as `nix.settings`.

Legacy configurations are mapped to their corresponding options under `nix.settings`
for backwards compatibility.

Various options settings in other nixos modules and relevant tests have been
updated to use structural setting for consistency.

The generation and validation of the configration file has been modified to
use `writeTextFile` instead of `runCommand` for clarity. Note that validation
is now mandatory as strict checking of options has been pushed down to the
derivation level due to freeformType consuming unmatched options. Furthermore,
validation can not occur when cross-compiling due to current limitations.

A new option `publicHostKey` was added to the `buildMachines`
submodule corresponding to the base64 encoded public host key settings
exposed in the builder syntax. The build machine generation was subsequently
rewritten to use `concatStringsSep` for better performance by grouping
concatenations.

nixos/test-runner: Fix execute() flakiness
Instead of using the magic string, we now just base64-encode everything
and check for a newline.

32d80aaaa5 nixos/tests/hibernate: install a system instead
Rather than relying on carefully avoiding touching the 9P-mounted
/nix/store, we instead install a small NixOS system, similar to
the installer tests, and boot from that.

This avoids the various pitfalls associated with trying to unsuspend
properly and trades off a bunch of boilerplate for what will hopefully
be a more reliable test.

Additionally, this test now actually tests booting the system using a
bootloader, rather than the previous method of just booting the kernel
directly.

nixos/tests/hibernate: Fix netcat flags
I'm not sure why 024b501907 used -q 0
because even netcat-openbsd has the -N flag which IMO is the better way
to shutdown the socket on EOF.

Our default netcat implementation has changed once again[1] in
3c3b82234a and we're now using LibreSSL's
implementation, which doesn't have a -q flag.

See https://github.com/NixOS/nixpkgs/pull/39634 for the pull request
introducing the switch.

affce1e246 nixos hibernate test: Use waitForOpenPort
There was one confusing recent failure of this:

http://cache.nixos.org/log/myla8bc17j8spmifdxmrz9jswxwsf5w6-vm-test-run-hibernate.drv

I don't have any real ideas on what could cause the problem but there is
at least one theoretical one: the system starts hibernating before the
listener process manages to open the TCP port for listening, and it can't
open it after resuming because not enough pages from the netcat binary
have been paged in (and as the 9p filesystem holding it is now toast,
they can't be loaded anymore).

e2372502d3 netcat: make netcat-openbsd the default netcat (#19411)
The motivation for this change is the following: As gnu-netcat,
e. g. does not support ipv6, it is not suitable as default netcat.

This commit also fixes all obvious build issues caused by this change.
