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.

Previously (in cfc18a7739), we forgot to
compare the algo at all. This means we keep the same ordering as before
by making the stuff we always have compared take priority.
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.

This is not really part of the evaluator: it is just an integration
between Boehm GC and Boost coroutines usable for any purpose. The
evaluator (merely) optionally uses it.
The implementation of `nix::createDirs` allows it to be a simple wrapper
around `std::filesystem::create_directories` as its return value is not
used anywhere.
throwing exceptions is fine, but throwing exceptions during exception
handling is hard enough to do correctly that we should just forbid it
entirely out of an overabundance of caution. in cases where terminate
is the correct answer the users of Finally must call it manually now.

Before, `-lnixutil` was just stuck in `nix-store.pc`, but that doesn't
seem so nice.
This prepares us to distribute `libnixutil` in a separate package if we
want, but it should be a good change either way. I suspect it wasn't
done before because libutil was an extra unstable interface, but I don't
think we need worry about that. *All* the C++ is less stable than the C
(or that's the goal at least).
For what it's worth, Lix also created this pkg-config file *en passant*
during their rename:
c97e17144e (diff-3c4f60cc44a0e35444c7f45331cfa50f76637118)
This re-enables support for older bwdgc versions without complicating
the code too much.
Coroutines generally only interfere with GC during source filtering,
so it's not too bad of a regression on older bdwgc.
This seems preferable over conditional compilation to enable the patch
etc; we've already spent a lot of complexity budget on this GC-coroutine
interaction...
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.
... so that we may perhaps later extend the interface.
Note that Nixpkgs' lib.warn already requires a string coercible
argument, so this is reasonable. Also note that string coercible
values aren't all strings, but in practice, for warn, they are.
Progress on #10832
This doesn't switch to auto-deriving the fields, but by defining `<=>`
we allow deriving `<=>` in downstream types where `Hash` is used.
Fixes assertion failure if outputsToInstall is empty by defaulting to the "out"
output. That is, behavior between the following commands should be consistent:
$ nix build --no-link --json .#nothing-to-install-no-out
error: derivation '/nix/store/eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee-nothing-to-install-no-out.drv' does not have wanted outputs 'out'
$ nix build --no-link --file default.nix --json nothing-to-install-no-out
error: derivation '/nix/store/eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee-nothing-to-install-no-out.drv' does not have wanted outputs 'out'
Real-world example of this issue:
$ nix build --json .#.legacyPackages.aarch64-linux.texlive.pkgs.iwona
error: derivation '/nix/store/dj0h6b0pnlnan5nidnhqa0bmzq4rv6sx-iwona-0.995b.drv' does not have wanted outputs 'out'
$ git rev-parse HEAD
eee33247cf6941daea8398c976bd2dda7962b125
$ nix build --json --file . texlive.pkgs.iwona
nix: src/libstore/outputs-spec.hh:46: nix::OutputsSpec::Names::Names(std::set<std::__cxx11::basic_string<char> >&&): Assertion `!empty()' failed.

1. Fix build by making the legacy SSH Storey's secret `logFD` setting
not a setting on Windows. (It doesn't make sense to specify `void *`
handles by integer cross-proccess, I don't think.)
2. Move some files that don't need to be Unix-only anymore back to their
original locations.

This turns errors like:
error: flake output attribute 'hydraJobs' is not a derivation or path
into errors like:
error: expected flake output attribute 'hydraJobs' to be a derivation or
path but found a set: { binaryTarball = «thunk»; build = «thunk»; etc> }
This change affects all InstallableFlake commands.

Both of these still needs their own actual documentation, but they are
at least now mentioned that they exist and what they're enabled by.

- Get a rump derivation goal: hook instance will come later, local
derivation goal will come after that.
- Start cleaning up the channel / waiting code with an abstraction.
By moving `host` to the config, we can do a lot further cleanups and
dedups. This anticipates a world where we always go `StoreReference` ->
`*StoreConfig` -> `Store*` rather than skipping the middle step too.
Progress on #10766
Progress on https://github.com/NixOS/hydra/issues/1164
This increases test coverage, and gets the worker protocol ready to be
used by Hydra.
Why don't we just try to use the store interface in Hydra? Well, the
problem is that the store interface works on connection pools, with each
opreation getting potentially a different connection, but the way temp
roots work requires that we keep one logical "transaction" (temp root
session) using the same connection.
The longer-term solution probably is making connections themselves
implement the store interface, but that is something that builds on
this, so I feel OK that this is not churn in the wrong direction.
Fixes#9584
We don't want to rely on how C assigns numbers for enums in the wire
format. Sure, this is totally determined by the ABI, but it obscures the
code and makes it harder to safely change the enum definition (should we
need to) without accidentally breaking the wire format.
Do this instead of an unchecked cast
I redid this to use the serialisation framework (including a unit test),
but I am keeping the reference to credit Jade for spotting the issue.
