jade 651cc0e5b4 fix: build with meson 1.5 also
nixpkgs delivered us the untimely gift of a meson 1.5 upgrade, which
*does* make our lives easier by allowing us to delete wrap generation
code, but it does so at the cost of renaming all rust crates in such a
way that the wrap logic cannot tolerate the new names on the old meson
version 😭.

It also means that support burden for this is going to be atrocious
until we either give in and vendor meson 1.5 or we make a CI target for
it. Neither seems appealing, though the latter is not super absurd for
ensuring we don't break nixpkgs unstable.

This commit causes meson 1.5 to ignore the .wrap files in subprojects/
entirely (since they have the wrong names lol) and instead use
Cargo.lock, so it now hard-depends on our workspace reshuffling
improvement.

It also deletes the hack that we were using to get the sources of Cargo
deps into meson by using a feature that went unnoticed when this code
was originally written: MESON_PACKAGE_CACHE_DIR:
8a202de6ec/mesonbuild/wrap/wrap.py (L490-L502)

jade dba615098d build: move to a Cargo workspace
This is purely to let Cargo's dependency resolver do stuff for us, we do
not actually intend to build this stuff with Cargo to begin with.

libutil/config: unify path setting types
There have been multiple setting types for paths that are supposed to be
canonicalised, depending on whether zero or one, one, or any number of paths is
to be specified. Naturally, they behaved in slightly different ways in the
code. Simplify things by unifying them and removing special behaviour (mainly
the "multiple paths type can coerce to boolean" thing).

Stop the logger in legacy commands again
Commit 0dd1d8ca1c included an accidental revert
of 1461e6cdda (actually slightly worse), leading
to the progress bar not being stopped properly when a legacy command was
invoked with `--log-format bar` (or similar options that show a progress bar).
Move the progress bar stopping code to its proper place again to fix this
regression.

Qyriad 95863b258b build: build lix-doc with Meson! 🎉
lix-doc is now built with Meson, with lix-doc's dependencies built as
Meson subprojects, either fetched on demand with .wrap files, or fetched
in advance by Nix with importCargoLock. It even builds statically.

Fixes #256.

Audrey Dutcher ae628d4af2 tests/functional/restricted: Don't use a process substitution
The <() process substitution syntax doesn't work for this one testcase
in bash for FreeBSD. The exact reason for this is unknown, possibly to
do with pipe vs file vs fifo EOF behavior. The prior behavior was this
test hanging forever, with no children of the bash process.

Maximilian Bosch 040e783232 flake: don't refetch unmodified inputs by recursive follows
Closes #460

I managed to trigger the issue by having the following inputs (shortened):

    authentik-nix.url = "github:nix-community/authentik-nix";
    authentik-nix.inputs.poetry2nix.inputs.nixpkgs.follows = "nixpkgs";

When evaluating this using

    nix-eval-jobs --flake .#hydraJobs

I got the following error:

    error: cannot update unlocked flake input 'authentik-nix/poetry2nix' in pure mode

The issue we have here is that `authentik-nix/poetry2nix` was written
into the `overrideMap` which caused Nix to assume it's a new input and
tried to refetch it (#460) or errored out in pure mode
(nix-eval-jobs / Hydra).

The testcase unfortunately only involves checking for the output log
and makes sure that something *is* logged on the first fetch so that
the test doesn't rot when the logging changes since I didn't
manage to trigger the error above with the reproducer from #460. In
fact, I only managed to trigger the `cannot update unlocked flake input`
error in this context with `nix-eval-jobs`.

jade 84543b459c doc: fix broken meson deps for various manuals outputs
This is incredibly haunted, but it can happen that you change libutil,
breaking the generation of the .json files, which then does not rebuild
the files. I don't expect they are slow to build, so it does not seem so
bad to just rebuild them every time instead of extracting a list of all
the possible deps.

We want to delete this nonsense anyway and replace it with generated
code.

Turns out strings do not like being resized to -4.

This was discovered while messing with the tests to remove unbuffer and

correct, and fixes a bug where with small window sizes where it would
ALSO truncate the attr names in addition to the optional descriptions.

It became less short after I found out that Linux was converting \n to

least solved by twiddling termios bits.
