tests/functional/help.sh calls nix-* commands with option --help
if nix is built without documentation the option --help throws an error
because the man page it wants to display is missing
Because of an objc quirk[1], calling curl_global_init for the first time
after fork() will always result in a crash.
Up until now the solution has been to set
OBJC_DISABLE_INITIALIZE_FORK_SAFETY for every nix process to ignore
that error.
This is less than ideal because we were setting it in package.nix,
which meant that running nix tests locally would fail because
that variable was not set.
Instead of working around that error we address it at the core -
by calling curl_global_init inside initLibStore, which should mean
curl will already have been initialized by the time we try to do so in
a forked process.

(cherry-picked and adapted from c7d97802e4)
`make check` was reverted too soon. The hacking guide wasn't brought
up to date with the new workflow, and it's not clear how to use
meson for everything.
This reverts commit 6f3045c2a2.
Now that we can run all tests with Meson, we want developers making code
changes to use it.
(Only the manual needs to be built with the build system, and that will
change shortly.)
This reverts commit b0bc2a97bf.
As discussed in our meeting, we should use a simplified version for the
libraries without the date or commit hash. This will make rebuilding a
lot faster in many cases.
Progress on #10379

By syncing with Nixpkgs, we reuse the same derivation, which is
generally a good idea, and has the benefit that it is transitively
a channel blocker.
Changes:
- https://github.com/NixOS/nixpkgs/pull/163313 (SuperSandro2000)
> nix: disable big-parallel for aws-sdk-cpp
> aws-sdk-cpp only takes ~1m52s on a 4 core machine under 50% load
> which does not justify the requirement on big parallel.
> Tested with `nix-build -A nixVersions.nix_2_6.aws-sdk-cpp`.
> I can finally build nix without requiring a big-parallel machine.
- https://github.com/NixOS/nixpkgs/pull/227506 (Artturin)
> nix: use [ ] instead null to empty requiredSystemFeatures
> fixes 'error: value is null while a list was expected' with 'nixpkgs.hostPlatform.gcc.arch = "x86_64";'
We don't apply any patches to it, and vendoring it locks users into
bugs (it hasn't been updated since its introduction in late 2021).

(cherry picked from commit 80405d06264f0de1c16ee2646388ab501df20628)
The idea is two-fold:
- Replace autotools with Meson
- Build each library in its own derivation
The interaction of these two features is that Meson's "subprojects"
feature (https://mesonbuild.com/Subprojects) allows us to have single
dev shell for building all libraries still, while also building things
separately. This allows us to break up the build without a huge
productivity lost.
I tested the Linux native build, and NetBSD and Windows cross builds.
Also do some clean ups of the Flake in the process of supporting new
jobs.
Special thanks to everyone that has worked on a Meson port so far,
@p01arst0rm and @Qyriad in particular.

This makes it match the current pattern:
- `package.nix` assumes deps are right version
- Overlay in `flake.nix` creates `*-nix` package variations
- Overlay manually passes in those packages to `package.nix`
Closes#10585
As it turns out, libseccomp maintains an internal syscall table and
validates each rule against it. This means that when using libseccomp
2.5.4 or older, one may pass `452` as syscall number against it, but
since it doesn't exist in the internal structure, `libseccomp` will refuse
to create a filter for that. This happens with nixpkgs-23.11, i.e. on
stable NixOS and when building Nix against the project's flake.
To work around that
* a backport of libseccomp 2.5.5 on upstream nixpkgs has been
scheduled[1].
* the package now uses libseccomp 2.5.5 on its own already. This is to
provide a quick fix since the correct fix for 23.11 is still a staging cycle
away.
It must not be possible to build a Nix with an incompatible libseccomp
version (nothing can be built in a sandbox on Linux!), so configure.ac
rejects libseccomp if `__SNR_fchmodat2` is not defined.
We still need the compat header though since `SCMP_SYS(fchmodat2)`
internally transforms this into `__SNR_fchmodat2` which points to
`__NR_fchmodat2` from glibc 2.39, so it wouldn't build on glibc 2.38.
The updated syscall table from libseccomp 2.5.5 is NOT used for that
step, but used later, so we need both, our compat header and their
syscall table 🤷

I've added the new local.mk to the package sources. While this
should not be needed for the build, it is the simplest solution,
and won't cause many extra rebuilds, because the file won't change
very often.
Add `runHook preInstallCheck` to the overriden `installCheckPhase` used
for the non-build case.
In particular, this allow the fix from 2a34510776
to also apply there.
Now `nix repl` an, in principle, work on that platform too.
Flake lock file updates:
• Updated input 'nixpkgs':
'github:NixOS/nixpkgs/2c9c58e98243930f8cb70387934daa4bc8b00373' (2023-12-31)

We don't just want to pass `--enable-gc=no`; we also want to make sure
boehmgc is not a dependency. Creating a nix-level configuration option
to do both, and then using that for the CI job, is more robust.
Changes:
- CPP variable is now `USE_READLINE` not `READLINE`
- `configure.ac` supports with new CLI flag
- `package.nix` supports with new configuration option
- `flake.nix` CIs this (along with no markdown)
Remove old Ubuntu 16.04 stop-gap too, as that is now quite old.
Motivation:
- editline does not build for Windows, but readline *should*. (I am
still working on this in Nixpkgs at this time, however. So there will
be a follow-up Nix PR removing the windows-only skipping of the
readline library once I am done.)
- Per
https://salsa.debian.org/debian/nix/-/blob/master/debian/rules?ref_type=heads#L27
and #2551, Debian builds Nix with readline. Now we better support and
CI that build configuration.
This is picking up where #2551 left off, ensuring we test a few more
things not merely have CPP for them.

It might seem obnoxious to have yet more configure flags, but I found
controlling both the unit and functional tests with one flag was quite
confusing because they are so different:
- unit tests depending on building, functional tests don't (e.g. when
we test already-built Nix)
- unit tests can be installed, functional tests cannot
- unit tests neeed extra libraries (GTest, RapidCheck), functional
tests need extra executables (jq).
- unit tests are run by `make check`, functional tests are run by `make
installcheck`
Really on a technical level, they seem wholly independent. Only on a
human level ("they are both are tests") do they have anything in common.
I had messed up the logic in cross builds because of this. Now I
split the flag in two (and cleaned up a few other inconsistencies), and
the logic fixed itself.

`configureFlags` only included `--with-boost` on Linux, which makes
local builds as outlined in `doc/manual/src/contributing/hacking.md`
fail when performed on macOS.
