eldritch horrors e6aab36d60 docs: put the manual build into a known tmpdir
this isn't strictly necessary, but it'll make it a lot easier to put the
generated files used by the autoconf build system in this directory too.
doing this now already will make the meson transition a lot easier later

eldritch horrors c1ae35d34a docs: don't compute SUMMARY.md during build
this would make meson build compatibility unnecessarily hard and
the cli does not change often enough to justify this complexity.

eldritch horrors d9bc197ff4 docs: don't compute rl-next.md during build
not sure why this was done the way it was considering that includes are
a feature the doc toolchain had previously. let's just always have some
kind of entry for the upcoming release in the dev manual builds even if
that means having a completely empty release notes chapter.

the release notes generation script isn't entirely functional right now
due to pre-commit hooks, but it's good enough for time being. we need a
better release process for notes anyway.

eldritch horrors 07ef9f9f5d docs: skip do custom include processing for mdbook
mdbook already does include processing of its own, and the custom
processing code has always admitted as much. we don't need it for
the mdbook build at this point if we run our preprocessors in the
right order, and maybe we can even have mdbook to return complete
pages to us that we only have to pass to lowdown without any more
preprocessing of our own.

eldritch horrors 14088e1ec5 docs: remove many link-to-self
for some reason these three were anchors, not links, but had they been
links they wouldn't've worked because they're not defined anywhere but
here. in the print version of the manual they're duplicated many times
over (creating id collisions), so we should better remove them anyway.

jade 1e74bffd5c pre-commit check for pragma once and ///@file
This is in our style guide, we can cheaply enforce it, let's do it.

check-executables-have-shebangs..........................................Passed

- hook id: check-headers

Missing pattern @file in file src/libexpr/value.hh

We found some header files that don't conform to the style guide.

The Lix style guide requests that header files:
- Begin with `#pragma once` so they only get parsed once
- Contain a doxygen comment (`/**` or `///`) containing `@file`, for
  example, `///@file`, which will make doxygen generate docs for them.

  When adding that, consider also adding a `@brief` with a sentence
  explaining what the header is for.

jade 54bc1f1b98 "but doctor, I AM the untrusted store": nix doctor had wrong trustedness
This probably snuck in in a refactor using truthiness or so. The
trustedness flag was having the optional fullness checked, rather than
the actual contained trust level.

Also adds some tests.

jade 0d37b99a15 build: enable libstdc++ assertions
Benchmarks say that it does not regress performance by more than 1%
(which is where it gets really hard to measure accurately anyhow).

Meson appears to be planning to do this for us without asking us in a
release we will get in the future, and it seems good enough to ship
today:

jade 0145d45806 nix-doc -> lix-doc, make self-contained in package.nix
package.nix previously needed this callPackage'd externally, which
didn't make a lot of sense to us since this is an internal dependency.
Thus we changed it to make it more self contained.

Qyriad 3ac2dd0613 package: put boehmgc patch logic in package.nix
In our view it really doesn't make sense to not have this in in
package.nix in some way. These patches aren't just for performance or
something -- Lix flat out doesn't build without these patches.

(Arguably that makes them a buildsystem responsibility as well, but that
can wait for when we're ready to start adding subproject fallback
dependency resolution to Meson.)

This is a step towards making `package.nix` more self-sufficient and
`callPackage`able without excessive external logic.

With this change the following command is enough to build Lix from out
of the flake:

nix-build -E 'let pkgs = import <nixpkgs> { }; in pkgs.callPackage
./package.nix { build-release-notes = false; inherit (pkgs.lib) fileset;
nix-doc = pkgs.callPackage ./nix-doc/package.nix { }; }'

Qyriad 5bac308c7c meson: fix warm nix3 CLI manual generation
`nix eval --write-to` refuses to write to a directory that exists at
all, so now we generate in a temporary directory, and copy the generated
tree to the build directory. This is equivalent to what the Make
buildsystem did, actually, but hopefully more robust.

Future work: documenting the doc generation architecture in the
top-level meson.build outline comment.

terru - a33c95be5b avoid markdown which the repl's :doc cannot handle
code blocks, if not surrounded by empty lines, have the language
tags (in these cases, always `nix`) show up in the output of :doc.

for example:

  nix-repl> :doc builtins.parseFlakeRef
  Synopsis: builtins.parseFlakeRef flake-ref

    Parse a flake reference, and return its exploded form.

    For example: nix builtins.parseFlakeRef
    "github:NixOS/nixpkgs/23.05?dir=lib"  evaluates to: nix { dir =
    "lib"; owner = "NixOS"; ref = "23.05"; repo = "nixpkgs"; type =
    "github"; }

is now instead:
  nix-repl> :doc builtins.parseFlakeRef
  Synopsis: builtins.parseFlakeRef flake-ref

    Parse a flake reference, and return its exploded form.

    For example:

      | builtins.parseFlakeRef "github:NixOS/nixpkgs/23.05?dir=lib"

    evaluates to:

      | { dir = "lib"; owner = "NixOS"; ref = "23.05"; repo = "nixpkgs"; type = "github"; }

(closes #225)

- Add `@should-start` to enable `nix repl` tests that error before
  entering the REPL
- Make sure to read all stdout output before comparing. This catches
  some extra output we were tossing out before!

this is not actually legal for nix! throwing exceptions in destructors

we received from the remote *twice* in some cases, and such cases will
cause an immediate terminate without active exception.
