helleandjade f659a1e638 Fix various links to anchors in documentation.
These are updates to several links in the documentation that are not
currently pointing to existing anchors in the documentation, these were
found using the unfinished version of the mdbook-linkchecker we are
working on.

Fixes include pointing them to the correct anchor, inserting anchors (in
updated html5 style, though debatable) and in the case of the historical
release notes, removing them, fixing #809.

Rebecca Turner e7463af241 justfile: enable just build install test
Previously, only the `install` target in the `justfile` took extra
`*OPTIONS`, which meant you could run `just build install test` (or
`just clean setup build install test` for a clean build). This is much
more convenient than `just build && just install && just test`.

However, sometimes you *do* need extra options for some of those other
targets, so over time they have gained extra arguments. But these
prevent you from chaining the targets together:

    $ just clean setup build install test
    rm -rf build
    meson setup build --prefix="$PWD/outputs/out" $mesonFlags build install test
    usage: meson [-h]
                 {setup,configure,dist,install,introspect,init,test,wrap,subprojects,rewrite,compile,devenv,env2mfile,reprotest,format,fmt,help}
                 ...
    meson: error: unrecognized arguments: install test
    error: Recipe `setup` failed on line 13 with exit code 2

As a compromise, I've renamed the targets with extra arguments to
include a `-custom` suffix, and added aliases for the old targets to
call the `-custom`-suffixed target with no extra arguments.

This makes it possible to run `just build install test` again, but keeps
the ability to run `just build-custom EXTRA_MESON_BUILD_ARGS`.

BONUS:
- Added `test-unit` and `test-integration`, because I always forget the
  arguments to run a particular test suite and the names of those test
  suites.
- Added doc comments to `lint` and `lint-fix`.

eldritch horrorsandjade b0d7a81613 fix tooling after include reorganization
clangd broke because it can't look through symlinks. compile_commands
manipulation does not fix it, clangd configuration does not fix it, a
vfs overlay does not fix it, and while a combination of those can fix
it with a bind mount in place that's just too cursed to even consider

Alois Wohlschlager c1746300a9 libexpr: generate builtins from data
Most builtins are now generated from data too, with two exceptions:
* Undocumented builtins, since supporting them would add complexity to the
  generator, the harms of the current implementation mostly don't apply, and
  the proper fix is to document them.
* `derivation` is somewhat magic (it is a function, but defined in the code as
  a constant), so the current treatment of having it separately documented is
  kept (for now, at least).
Since it is slightly easier to do and probably a good idea anyway, the builtin
function registrations generated this way are now processed directly in code
and don't go through global variables any more.
Unfortunately, a slight breaking change is introduced because the order of the
builtins' names in the symbol table changes. Hopefully, this will turn out to
not matter in practice.

Alois Wohlschlager 21fc0ddce5 libutil: generate experimental and deprecated features from data
Currently, a bunch of documentation is generated by embedding parts of it in
the nix executable, getting it out again by running it, and then postprocessing
the output. This is bad, since it creates a pointless dependency of the
documentation on the executable, and also makes documentation generation
impossible when cross-compiling.
Instead, both the code and the documentation should be generated from data, see
https://git.lix.systems/lix-project/lix/issues/292 . Here we start applying
this approach to the experimental and deprecated features, which are done in
one go since the technical implementation is very similar.
Of course, the actual benefits are not realised yet, since the offending
pattern is used in several more places. These will be fixed later.

Jade LovelaceandQyriad 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
```

Jade Lovelace 748d8310fa Fix the pages in the manual for Lix
This doesn't comprehensively fix everything outdated in the manual, or
make the manual greatly better, but it does note down where at least
jade noticed it was wrong, and it does fix all the instances of
referencing Nix to conform to the style guide to the best of our
ability.

A lot of things have been commented out for being wrong, and there are
three types of FIXME introduced:

- FIXME(Lix): generically Lix needs to fix it
- FIXME(Qyriad): re https://git.lix.systems/lix-project/lix/issues/215
- FIXME(meson): docs got outdated by meson changes and need rewriting

I did fix a bunch of it that I could, but there could certainly be
mistakes and this is definitely just an incremental improvement.

Qyriad b913a939b0 meson: flip the switch!!
This commit makes Meson the default buildsystem for Lix.
The Make buildsystem is now deprecated and will be removed soon, but has
not yet, which will be done in a later commit when all seems good. The
mesonBuild jobs have been removed, and have not been replaced with
equivalent jobs to ensure the Make buildsystem still works.

The full, new commands in a development shell are:

$ meson setup ./build "--prefix=$out" $mesonFlags

(A simple `meson setup ./build` will also build, but will do a different
thing, not having the settings from package.nix applied.)

$ meson compile -C build
$ meson test -C build --suite=check
$ meson install -C build
$ meson test -C build --suite=installcheck

(Check and installcheck may both be done after install, allowing you to
omit the --suite argument entirely, but this is the order package.nix
runs them in.)

If tests fail and Meson helpfully has no output for why, use the
`--print-error-logs` option to `meson test`. Why this is not the default
I cannot explain.

If you change a setting in the buildsystem, most cases will
automatically regenerate the Meson configuration, but some cases, like
trying to build a specific target whose name is new to the buildsystem
(e.g. `meson compile -C build src/libmelt/libmelt.dylib`, when
`libmelt.dylib` did not exist as a target the last time the buildsystem
was generated), then you can reconfigure using new settings but
existing options, and only recompiling stuff affected by the changes:

$ meson setup --reconfigure build

Note that changes to the default values in `meson.options` or in the
`default_options :` argument to project() are NOT propagated with
`--reconfigure`.

If you want a totally clean build, you can use:

$ meson setup --wipe build

That will work regardless of if `./build` exists or not.

Specific, named targets may be addressed in
`meson build -C build <target>` with the "target ID" if there is one,
which is the first string argument passed to target functions that
have one, and unrelated to the variable name, e.g.:

libexpr_dylib = library('nixexpr', …)

can be addressed with:

$ meson compile -C build nixexpr

All targets may be addressed as their output, relative to the build
directory, e.g.:

$ meson compile -C build src/libexpr/libnixexpr.so

But Meson does not consider intermediate files like object files
targets. To build a specific object file, use Ninja directly and
specify the output file relative to the build directory:

$ ninja -C build src/libexpr/libnixexpr.so.p/nixexpr.cc.o

To inspect the canonical source of truth on what the state of the
buildsystem configuration is, use:

$ meson introspect

Have fun!

eldritch horrors 279e30e7ef build: replace changelog-d with local script
hacking changelog-d to support not just github but also forgejo and
gerrit is a lot more complicated than it's worth, even moreso since
the entire thing can just as well be done with ~60 lines of python.
this new script is also much cheaper to instantiate (being python),
so having it enabled in all shells is far less of a hassle.

we've also adjusted existing release notes that referenced a gerrit
cl to auto-link to the cl in question, making the diff a bit bigger
