Masanori Ogino 8875db4976 nixos/sshd: update kexAlgorithms, fix links
The `curve25519-sha256` key exchange method is defined in RFC 8731 that
is identical to curve25519-sha256@libssh.org. OpenSSH supports the
method since version 7.4, released on 2016-12-19. It is literally a
violation of the "both in Secure Secure Shell and Mozilla guidelines"
rule, but it provides essentially the same but a future-proof default.

Also, links to the Mozilla OpenSSH guidelines are updated to refer to
the current place.

nixos/treewide: Move rename.nix imports to their respective modules
A centralized list for these renames is not good because:
- It breaks disabledModules for modules that have a rename defined
- Adding/removing renames for a module means having to find them in the
central file
- Merge conflicts due to multiple people editing the central file

nixos/sshd: validate ssh configs during build

nixos/sshd: validate ssh configs during build
With `sshd -t` config validation for SSH is possible. Until now, the
config generated by Nix was applied without any validation (which is
especially a problem for advanced config like `Match` blocks).

When deploying broken ssh config with nixops to a remote machine it gets
even harder to fix the problem due to the broken ssh that makes reverts
with nixops impossible.

This change performs the validation in a Nix build environment by
creating a store path with the config and generating a mocked host key
which seems to be needed for the validation. With a broken config, the
deployment already fails during the build of the derivation.

The original attempt was done in #56345 by adding a submodule for Match
groups to make it harder screwing that up, however that made the module
far more complex and config should be described in an easier way as
described in NixOS/rfcs#42.

Mostly a bugfix release, no major backwards-incompatible changes.

Remove deprecated `UsePrivilegeSeparation` option,
which is now mandatory.

sshd.nix: Alternative fix for #19589
AFAICT, this issue only occurs when sshd is socket-activated. It turns
out that the preStart script's stdout and stderr are connected to the
socket, not just the main command's. So explicitly connect stderr to
the journal and redirect stdout to stderr.

Revert "sshd: separate key generation into another service"
This reverts commit 1a74eedd07. It
breaks NixOps, which expects that

  rm -f /etc/ssh/ssh_host_ed25519_key*
  systemctl restart sshd
  cat /etc/ssh/ssh_host_ed25519_key.pub

works.

Fix setting programs.ssh.setXAuthLocation
The configuration { services.openssh.enable = true;
services.openssh.forwardX11 = false; } caused
programs.ssh.setXAuthLocation to be set to false, which was not the
intent. The intent is that programs.ssh.setXAuthLocation should be
automatically enabled if needed or if xauth is already available.
