perl: run `initLibStore()` on `openStore()`

John Ericson 45fa297e40 Factor out InstallableStorePath to its own file, dedup
`nix app` had something called `InstallableDerivedPath` which is
actually the same thing. We go with the later's name because it has
become more correct.

I originally did this change (more hurriedly) as part of  --- a
mini store-only Nix and a full Nix need to share this code. In the first
RFC meeting for https://github.com/NixOS/rfcs/pull/134 we discussed how
some splitting of the massive `installables.cc` could begin prior, as
that is a good thing anyways. (@edolstra's words, not mine!) This would
be one such PR.

Jörg Thalheim f20d3726dd advertise transport encoding in http transfers to
tl;dr: With this 1 line change I was able to get a speedup of 1.5x on 1Gbit/s
wan connections by enabling zstd compression in nginx.

Also nix already supported all common compression format for http
transfer, webservers usually only enable them if they are advertised
through the Accept-Encoding header.

This pull requests makes nix advertises content compression support for
zstd, br, gzip and deflate.

It's particular useful to add transparent compression for binary caches
that serve packages from the host nix store in particular nix-serve,
nix-serve-ng and harmonia.

I tried so far gzip, brotli and zstd, whereas only zstd was able to bring
me performance improvements for 1Gbit/s WAN connections.

The following nginx configuration was used in combination with the
[zstd module](https://github.com/tokers/zstd-nginx-module) and
[harmonia](https://github.com/nix-community/harmonia/)

```nix
{
  services.nginx.virtualHosts."cache.yourhost.com" = {
    locations."/".extraConfig = ''
      proxy_pass http://127.0.0.1:5000;
      proxy_set_header Host $host;
      proxy_redirect http:// https://;
      proxy_http_version 1.1;
      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
      proxy_set_header Upgrade $http_upgrade;
      proxy_set_header Connection $connection_upgrade;

      zstd on;
      zstd_types application/x-nix-archive;
    '';
  };
}
```

For testing I unpacked a linux kernel tarball to the nix store using
this command `nix-prefetch-url --unpack https://cdn.kernel.org/pub/linux/kernel/v6.x/linux-6.1.8.tar.gz`.

Before:

```console
$ nix build && rm -rf /tmp/hello  && time ./result/bin/nix copy --no-check-sigs --from https://cache.thalheim.io --to 'file:///tmp/hello?compression=none' '/nix/store/j42mahch5f0jvfmayhzwbb88sw36fvah-linux-6.1.8.tar.gz'

After:

John Ericson a47e055e09 Move trustedUsers and allowedUsers to separate config struct
These settings are not needed for libstore at all, they are just used by
the nix daemon *command* for authorization on unix domain sockets. My
moving them to a new configuration struct just in that file, we avoid
them leaking anywhere else.

Also, it is good to break up the mammoth `Settings` struct in general.
Issue  tracks this.

The message is not changed because I do not want to regress in
convenience to the user. Just saying "this connection is not trusted"
doesn't tell them out to fix the issue. The ideal thing to do would be
to somehow parameterize `processCommand` on how the error should be
displayed, so different sorts of connections can display different
information to the user based on how authentication is performed for the
connection in question. This, however, is a good bit more work, so it is
left for the future.

This came up with me thinking about the tcp:// store (). The larger
project is not TCP *per se*, but the idea that it should be possible for
something else to manage access control to services like the Nix Daemon,
and those services simply trust or trust the incoming connection as they
are told. This is a more capability-oriented way of thinking about trust
than "every server implements its own auth separately" as we are used to today.

Its very great that libstore itself already implements just this model,
and so via this refactor I basically want to "enshrine" that so it
continues to be the case.

John Ericson 479c011784 Get rid of the authHook parameter on processConnection
This is (morally) dead code.

As @edolstra pointed out in
https://github.com/NixOS/nix/pull/5226#discussion_r1073470813, this is
no longer needed.

I created this in 8d4162ff9e, so it is
fitting that I now destroy it :).

perl: run initLibStore() on openStore()
Since  it's mandatory that `initLibStore()` is called for store
operations. However that's not the case when running `openStore()` in
Perl using the perl-bindings. That breaks e.g. `hydra-eval-jobset` when
built against Nix 2.13 which uses small portions of the store API.

With the switch to C++20, the rules became more strict, and we can no
longer initialize base classes. Make them comments instead.

(BTW
https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2021/p2287r1.html
this offers some new syntax for this use-case. Hopefully this will be
adopted and we can eventually use it.)

`&` without space before is far more common on this codebase than I
thought, so it is not worth changing just this one file. Maybe we will
adopt a formatter someday but until then this is fine.

Robert Hensing 60d48eda23 nix flake show: Ignore empty attrsets
For frameworks it's important that structures are as lazy as possible
to prevent infinite recursions, performance issues and errors that
aren't related to the thing to evaluate. As a consequence, they have
to emit more attributes than strictly (sic) necessary.
However, these attributes with empty values are not useful to the user
so we omit them.

Handle the case where none of getActualAttrPaths() actually exists,
in which case instead of returning an empty vector.

This fixes the case where the user misspells the attribute name in nix
search. Instead of getting no search results, now it shows an error with
suggestions.

Also remove InstallableFlake::getCursor() override since it's now
equivalent to the base class version.
