This will avoid some out-of-memory issues in GitHub actions that result
from num jobs > 1 and num cores = 4. Once we only have the Meson build
system, this problem should go away, and we can reenable these jobs.
Special thanks to everyone that has worked on a Meson port so far,
@p01arst0rm and @Qyriad in particular.

I hope this will make it easier to maintain, and also make it easier for
others to assist with porting the rest of the build system to Meson.

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.

Manually tested by printing to stderr in both branches (sp in os
stack, or not), and triggering a GC in a filterSource function,
e.g.:
let
generateTree = n: if n == 0 then "ha" else { left = generateTree (n - 1); right = generateTree (n - 1); };
in
builtins.deepSeq (generateTree 18) ...
Note that the darwin still uses the strategy of disabling GC, despite
having an implementation that compiles. The proper solution will be
enabled and tested later.
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`
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.
`nix-env -qaP`'s output has changed a bit because of https://github.com/NixOS/nix/issues/10132.
Although that's a bit annoying, it isn't nearly as problematic as the
evaluation changes that this test is supposed to catch. So it's find to
just update the hash for the time being and fix the issue later
(properly fixing the issue will very likely change the hash any way).
`NIX_HARDENING_ENABLE` causes `_FORTIFY_SOURCE` to be defined.
This isn't compatible with `-O0`, and the compiler will happily remind
us about it at every call, spamming the terminal with warnings and stack
traces.
We don't really care hardening in that case, so just disable it if we
pass `OPTIMIZE=0`.
Just `stdenv.isDarwin` isn't enough because it doesn't apply to the
build platform, which mean that cross packages building from darwin to
another platform will have `isDarwin` set to false.
Replace it by `stdenv.buildPlatform.isDarwin`.
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.

The thing we wanted to test was that building Nix without building or
running tests, and without depending on libraries only needed by tests,
works.
But since 6c8f4ef350, we can also install
unit tests, and during the conversion to using `package.nix` this
started happening more often (they go to a separate output though, so
this should be fine).
This adds more `... = false` to restore the original intent: don't run
unit test or functional tests, and don't install unit tests.
This was last upgraded in 788008385e, but
the version in Nixpkgs is a now a lot newer. I think the custom was
added to get ahead of Nixpkgs before, and so now that we are in fact
behind, it is no longer needed.
The Perl bindings are not part of Nix, but a downstream package, so they
don't belong in `package.nix`.
They don't really belong as an attribute on `nix` either, but we can
just leave that interface as is for now.
The problem was since switching to use libgit2, we had a package in our
closure (`http-parser`) that was always trying to build as a shared
object.

Flake lock file updates:
• Updated input 'nixpkgs':

Today, with the tests inside a `tests` intermingled with the
corresponding library's source code, we have a few problems:
- We have to be careful that wildcards don't end up with tests being
built as part of Nix proper, or test headers being installed as part
of Nix proper.
- Tests in libraries but not executables is not right:
- It means each executable runs the previous unit tests again, because
it needs the libraries.
- It doesn't work right on Windows, which doesn't want you to load a
DLL just for the side global variable . It could be made to work
with the dlopen equivalent, but that's gross!
This reorg solves these problems.
There is a remaining problem which is that sibbling headers (like
`hash.hh` the test header vs `hash.hh` the main `libnixutil` header) end
up shadowing each other. This PR doesn't solve that. That is left as
future work for a future PR.

Closes#9343
See that issue for motivation.
Installing these is disabled by default, but we enable it (and the
additional output we want isntall these too so as not to clutter the
existing ones) to use in cross builds and dev shells.
This adds simple tests of the commit signature verification mechanism of
fetchGit and its flake input wrapper.
OpenSSH is added to the build dependencies since it's needed to create
a key when testing the functionality. It is neither a built- nor a
runtime dependency.
