This is not ca-derivations. We don't care about self-references or any of the
rewriting or stuff like that; if you want something like that, write
your user code so it figures out where it is.
The reason I want to do this is for integrating other build systems with
Lix: if you're importing something built *outside the store* with a
non-Nix build system, it makes no sense to put it in an input-addressed
path since it's not possible to come up with a derivation for it.
But you need *some* hash, so the output hashing is the most sensible option.
It is also nice because of not needing trusted user privileges to import
it, since the hash describes the exact contents of the output path.
We use this feature (implemented externally to Lix; this CL eliminates
that step) at Mercury to integrate buck2 with Nix on the output side: we
import things to the Nix store as ca paths with references.
These can then be consumed by Nix language with:
```
# Hack from https://git.lix.systems/lix-project/lix/issues/402#issuecomment-5889
path:
builtins.appendContext path {
${path} = {
path = true;
};
}
```
Test plan:
```
$ nix store add-path --references-list xx-refs-list ./README.md
/nix/store/szcwnm13d9gmxx8fly0bz82l42jgysw6-README.md
$ cat xx-refs-list
/nix/store/g9hhwjbkdrw0wnbd3axfs4icyb37nr6b-bash-interactive-5.3p3

A friend reported that this is rebuilding, which doesn't make any sense
because nixpkgs also has a lix from nightly that surely has the same
dependency and thus it surely should be built on hydra, right?
Turns out no, since they were overriding the requiredSystemFeatures to
remove big-parallel. Silly, but we can match that and get cache hits.

This will probably get the implementation of the fixtures revised when
we land the new extraction code, but we are setting it up to be generic
against that.
The operator-> thing is kind of a crime. But it also makes the code
vastly more readable so it's impossible to say if it's bad or not.

Fixes: https://git.lix.systems/lix-project/lix/issues/973
Information about which commands were executed is really valuable to
debug Lix and is much more user relevant than the vast majority of the
e.g. build loop junk printed at debug level. Currently we have a *whole
lot* of call sites where we call execv* which should probably be cleaned
up, but that's future work.
I chose to print argv0 rather than the executable path if these differ,
since the code is shorter and since the command could be a fully
resolved symlink or so where argv0 is the actual command name being run.
However, it's not exactly *hard* to write std::ranges::drop_view(args,
1).

Also adds an assert that store path hash part length is what we expect
because it's alarmingly easy to forget to truncate a hash before
throwing it into there. It's kind of messy code, someone could improve
it more later.

This results in anything that uses nixpkgs getting stopped in the
debugger inside of nixpkgs internals, which are usually irrelevant.
Let's default to the more useful option.

The reason this gets hit is because of the debugger in flakes. Otherwise
you never have a repl in pure mode anyway.
We evaluate the repl-overlay file in impure mode but this doesn't do
what one would initially expect.

idk how this mistake happened but it was really confusing to figure out
which one of these was right, so let's get rid of the impostor.

This was an absolute nightmare to diagnose. It turns out there's a
kernel bug: poll with events = POLLHUP will receive an event for NOT
POLLHUP internally in the kernel, delete their event subscription, and
then not receive events for any HUP later. lol! lmao!!
We choose to use plain old EVFILT_READ because the watched fd can be
either a socket or a pipe and it's preferable to eat some spurious
wakeups than have separate paths for those. The alternative is using
EVFILT_SOCK, a private API that's existed for years and which netty
uses for its sockets, but that doesn't work on pipes.

Well, I was trying to figure out
https://git.lix.systems/lix-project/lix/issues/729 in which this feature
is clearly just broken on macOS, but frustratingly, it seems that it
*does* work, except for the daemon. um........ sure.

Yikes!! I wonder if we have any other ones of these that just .. didn't
get added to a meson file?

This is *just* in output messages that look relatively like the FOD
failure message. It's not great that we inconsistently use the old
format in random places.

Well that is a mess. I don't like breaking derivation compatibility,
but I like non-deterministic evaluation much less.
We can break compat if we own up to it, which this does.

This is a redesign from 9b1f3cbc13 where
this was introduced.
I deleted the AbstractConfig::toKeyValue since it was conspicuously and
obviously broken for two years since 450e5ec618.
I asked myself if anyone was using it, given that it only emitted
settings that were aliases (broken!), and found that nobody used it.
The motivation for this change is the same for only emitting overridden
settings to the protocol: the nix inside there may not be able to parse
our defaults, as is the case of CppNix since the consensual
accept-flake-config was added to Lix.

Missing these is really annoying, causes massive problems for debugging
(if you don't to enable build logs), and there's basically no reason we
can't just always show them.
In the future we might want to emit these to syslog/systemd/etc, but for
now let's just always print them to the console.

Found at work; the message implies you aren't trusted-user when it
actually is that ignore-liveness is always rejected by the daemon.
Whether this command is actually a good idea varies substantially of
course.

This is necessary to cleanly and unambiguously transition to using
forgejo issues, since we now control our own destiny.
If we ban unprefixed numbers for a couple of releases, we ensure there
are no releases in active support with the wrong unprefixed number
semantics that could receive backports.

We don't want any of this github integration stuff since it won't do
anything, flakes don't support subdirs properly and maintaining a second
flake is pointless and annoying, and then the rest is lix formatting
standards hitting n-e-j.
Yeet!

We will link to boehm inside of the test suite if it depends on libexpr
but we don't need it for other tests.
For anything linking to libexpr internally, just like externally, it
needs to link to boehm.
Likewise with kj and libutil (or really any lix), so we should just make
it automatic.

This is required for moving n-e-j into tree with good meson support: it
needs to be able to include `<lix/config.h>`.

Since we include kj from a header, we need to add a dependency to force
downstreams to also have it as a declared dependency or at least put it
in their include dir paths.
Given kj is what it is, this is basically unavoidable that this
dependency is visible.
