eldritch horrors 4d8c66ec6f add aarch64-linux as a cross-build target
we want to be sure we can cross-build to aarch64 for releases, add a
target to our crossSystems list to make those cheacks easier to run.

Quantum Jump 6e0ca02425 Fix dry-run flag for nix-collect-garbage
`nix-collect-garbage --dry-run` previously elided the entire garbage
collection check, meaning that it would just exit the script without
printing anything.

This change makes the dry run flag instead set the GC action to
`gcReturnDead` rather than `gcDeleteDead`, and then continue with the
script. So if you set `--dry-run`, it will print the paths it *would*
have garbage collected, but not actually delete them.

I filed a bug for this: lix-project/lix#432 but then realised I could give fixing it a go myself.

libexpr/flake: allow automatic rejection of configuration options from flakes
The `allow-flake-configuration` option allows the user to control whether to
accept configuration options supplied by flakes. Unfortunately, setting this
to false really meant "ask each time" (with an option to remember the choice
for each specific option encountered). Let no mean no, and introduce (and
default to) a separate value for the "ask each time" behaviour.

Delan Azabani b2944d93a6 Reject fully-qualified URLs in 'from' argument of nix registry add
We previously allowed you to map any flake URL to any other flake URL,
including shorthand flakerefs, indirect flake URLs like `flake:nixpkgs`,
direct flake URLs like `github:NixOS/nixpkgs`, or local paths.

But flake registry entries mapping from direct flake URLs often come
from swapping the 'from' and 'to' arguments by accident, and even when
created intentionally, they may not actually work correctly.

This patch rejects those URLs (and fully-qualified flake: URLs), making
it harder to swap the arguments by accident.

Fixes #181.

This modifies all scripts that use a `/bin/sh` shebang to `/usr/bin/env
bash`, including currently POSIX-compliant ones, to prevent any future
confusion.

Robert Hensing d86009bd76 Add build-dir setting, clean up default TMPDIR handling
This is a squash of upstream PRs #10303, #10312 and #10883.

fix: Treat empty TMPDIR as unset

Fixes an instance of

    nix: src/libutil/util.cc:139: nix::Path nix::canonPath(PathView, bool): Assertion `path != ""' failed.

... which I've been getting in one of my shells for some reason.
I have yet to find out why TMPDIR was empty, but it's no reason for
Nix to break.

fix: Treat empty XDG_RUNTIME_DIR as unset

See preceding commit. Not observed in the wild, but is sensible
and consistent with TMPDIR behavior.

jade 59b5965bbf doc: Write an index of environment variables used in testsuite
This was originally going to be just the testsuite but I kinda just
documented all of them.

I am tired of us not documenting these. This is a starting point to
producing an actually good index. I would like to enforce it in a
pre-commit hook eventually that we document all environment variables
used in Lix itself, even if it is terse dev facing docs.

This is full of a bunch of TODOs caused by auditing code. They should
probably be done at some point.

Qyriad afeaa2371c docs: enable non-default TOC folding
Folding by default would prevent things like "Ctrl+F for nix-env" from
working trivially, but the user should be able to fold if they want to.

terru - d8e452a91b document context-dependent keywords
Documents some of the weirdness of __curPos and the or keyword.
This does not fit well into any existing section for either of
them, though the use of or as a quasi-operator is mentioned in
the section on operators.

Addresses lix-project/lix#353

alois31 f047e4357b libstore/build: always enable seccomp filtering and no-new-privileges
Seccomp filtering and the no-new-privileges functionality improve the security
of the sandbox, and have been enabled by default for a long time. In
lix-project/lix#265 it was decided that they
should be enabled unconditionally. Accordingly, remove the allow-new-privileges
(which had weird behavior anyway) and filter-syscall settings, and force the
security features on. Syscall filtering can still be enabled at build time to
support building on architectures libseccomp doesn't support.

jade c97e17144e packaging: rename nixexpr -> lixexpr and so on
This breaks downstreams linking to us on purpose to make sure that if
someone is linking to Lix they're doing it on purpose and crucially not
mixing up Nix and Lix versions in compatibility code.

We still need to fix the internal includes to follow the same schema so
we can drop the single-level include system entirely. However, this
requires a little more effort.

This adds pkg-config for libfetchers and config.h.

Migration path:
expr.hh      -> lix/libexpr/expr.hh
nix/config.h -> lix/config.h

To apply this migration automatically, remove all `<nix/>` from
includes, so: `#include <nix/expr.hh>` -> `#include <expr.hh>`. Then,
the correct paths will be resolved from the tangled mess, and the
clang-tidy automated fix will work.

Then run the following for out of tree projects:

```
lix_root=$HOME/lix
(cd $lix_root/clang-tidy && nix develop -c 'meson setup build && ninja -C build')
run-clang-tidy -checks='-*,lix-fixincludes' -load=$lix_root/clang-tidy/build/liblix-clang-tidy.so -p build/ -fix src
```
