When we start unrecursivifying (sp?) things, Rust's borrow checker
is going to be a headache; its magic only works when you use the CPU
stack as your call stack.
Fixing the borrow checker issues usually involves adding lots of
`clone()`s. Right now `NixList` is the only variant of `Value` that
isn't cheap to clone() -- all the others are either a wrapper around
Rc or else are of bounded size.
Note that this requires dropping the `DerefMut for NixList` instance
and using `Vec<Value>` instead in those situations.

When comparing Nix values for equality, an issue can occur where
recursive values contain thunks to themselves which causes borrow
errors when forcing them for comparison later down the line.
To work around this we clone the values for now. There might be some
optimisations possible like checking for thunk equality directly and
short-circuiting on that (we have to check what Nix does).

When passing multiple arguments, every intermediate callable needs to
be forced as this is expected by the VM's call_value function.
Also adds a debug assertion for this which makes it easier to spot
exactly what went wrong.

This function covers builtins.genericClosure, seemingly including
weird behaviour around the order in which the work set is processed.
For some reason, in C++ Nix the test expectation is written in XML
which we do not yet support, so I have created a new expectation file
using `nix-instantiate --eval --strict` on the file (yes, using C++
Nix).

This implementation closely follows the original implementation in
Nix, including the use of an equality-based "set" structure to track
keys that have already been processed.
Note that this test does not yet enable the `notyetpassing` test for
builtins.genericClosure because (for as of yet unknown reasons) this
test compares against XML output (however, evaluating the test case
actually does work).
This takes us one step closer to nixpkgs eval.

**TL;DR:**
- Delete half-baked packaging attempts (`job.nix`, `token.nix`).
- Ensure golang code compiles.
- Some "packages" were being treated like "programs" presumably for
debugging/testing purposes back when I was working on this. Make those
behave like libraries.
- Remove stale imports.
- Fix syntax errors.
- Miscellaneous other chores.
- Drop `shell.nix` and `use_nix` directive.

Something I missed last time reading through the process documentation
is that you can use a combination of `process` and `process-wait` to
determine the exit status of a child process *and* read from its
standard output. With `process*` we could even capture stderr, but we
probably want it mounted to the parent process' stderr anyways.

**TL;DR:**
Most of these changes predicate behavior on the platform:
- At buildtime this is `localSystem == $something`. (`localSystem` is from
`readTree`)
- At runtime this is `(memq window-system '(ns))`.
- Add `coreutils` so `dired` listing with `--group-directories-first` works
because that flag depends on the GNU version of `ls`.
**Background:**
I need to support a bunch of OSX users at $WORK. As such, I'm planning
on using my MBP for the next few weeks to build empathy for our
userbase and polish some currently rough edges.
If I'm going to get an serious work done, I need my Emacs setup. Step
one is making sure it can build and run.

By re-using the nix_2_3 expression from nixpkgs we are no longer stuck
with the 2021 expression from Nix's release.nix and the resulting
derivation has a shape that other expressions in nixpkgs expect (e.g.
nix-serve), so we can actually overlay our fork into the nix_2_3
attribute. This should reduce duplication on e.g. whitby.
Since there is no nixUnstable expression in nixpkgs anymore, it expects
a Nix release tarball which we produle using the appropriate release.nix
job from the repository. Sadly there is some trickery involved in
getting it to respect localSystem, since the tarball job is not based on
the passed in systems list.

cl/5832 added a global system parameter to depot which allowed specifying
what `system` should be used for nixpkgs and all depot derivations
(assuming a native compilation case) which was implemented in cl/5846.
This allows instantiating derivations for a different system than
whatever builtins.currentSystem happens to be. This is useful for
debugging, allows you to schedule builds on build servers for
other platforms or build for architectures that are a subset of
the one you are running (e.g. i686-linux).
This change eliminates all remaining uses of builtins.currentSystem
which could lead to an inconsistent combination of `system` values
when passing `localSystem`.
