nixos: explicitely set security.wrappers ownership
This is slightly more verbose and inconvenient, but it forces you
to think about what the wrapper ownership and permissions will be.

nixos/security/wrappers: check that sources exist
Add a shell script that checks if the paths of all wrapped programs
actually exist to catch mistakes. This only checks for Nix store paths,
which are always expected to exist at build time.

nixos/security/wrappers: use fixed defaults
To keep backward compatibility and have a typing would require making
all options null by default, adding a defaultText containing the actual
value, write the default value logic based on `!= null` and replacing
the nulls laters. This pretty much defeats the point of having used
a submodule type.

nixos/security/wrappers: make well-typed
The security.wrappers option is morally a set of submodules but it's
actually (un)typed as a generic attribute set. This is bad for several
reasons:

1. Some of the "submodule" option are not document;
2. the default values are not documented and are chosen based on
   somewhat bizarre rules (issue #23217);
3. It's not possible to override an existing wrapper due to the
   dumb types.attrs.merge strategy;
4. It's easy to make mistakes that will go unnoticed, which is
   really bad given the sensitivity of this module (issue #47839).

This makes the option a proper set of submodule and add strict types and
descriptions to every sub-option. Considering it's not yet clear if the
way the default values are picked is intended, this reproduces the current
behavior, but it's now documented explicitly.

nixos/wrappers: fix applying capabilities
With libcap 2.41 the output of cap_to_text changed, also the original
author of code hoped that this would never happen.
To counter this now the security-wrapper only relies on the syscall
ABI, which is more stable and robust than string parsing. If new
breakages occur this will be more obvious because version numbers will
be incremented.
Furthermore all errors no make execution explicitly fail instead of
hiding errors behind debug environment variables and the code style was
more consistent with no goto fail; goto fail; vulnerabilities (https://gotofail.com/)

Revert "apparmor: fix and improve the service"
This reverts commit fb6d63f3fd.

I really hope this finally fixes #99236: evaluation on Hydra.
This time I really did check basically the same commit on Hydra:
https://hydra.nixos.org/eval/1618011

Right now I don't have energy to find what exactly is wrong in the
commit, and it doesn't seem important in comparison to nixos-unstable
channel being stuck on a commit over one week old.

nixos/security/wrapper: ensure the tmpfs is not world writeable
The /run/wrapper directory is a tmpfs. Unfortunately, it's mounted with
its root directory has the standard (for tmpfs) mode: 1777 (world writeable,
sticky -- the standard mode of shared temporary directories). This means that
every user can create new files and subdirectories there, but can't
move/delete/rename files that belong to other users.

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

Michael Weiss 351f5fc585 fuse3: init at 3.1.1
This includes fuse-common (fusePackages.fuse_3.common) as recommended by
upstream. But while fuse(2) and fuse3 would normally depend on
fuse-common we can't do that in nixpkgs while fuse-common is just
another output from the fuse3 multiple-output derivation (i.e. this
would result in a circular dependency). To avoid building fuse3 twice I
decided it would be best to copy the shared files (i.e. the ones
provided by fuse(2) and fuse3) from fuse-common to fuse (version 2) and
avoid collision warnings by defining priorities. Now it should be
possible to install an arbitrary combination of "fuse", "fuse3", and
"fuse-common" without getting any collision warnings. The end result
should be the same and all changes should be backwards compatible
(assuming that mount.fuse from fuse3 is backwards compatible as stated
by upstream [0] - if not this might break some /etc/fstab definitions
but that should be very unlikely).

My tests with sshfs (version 2 and 3) didn't show any problems.

See #28409 for some additional information.
