There's various bits and pieces in tvix-cli that use both the store and
evaluator, as well as nix-compat. For example, builtins.derivation, as
well as the reference scanning implementation.
This "glue code" currently isn't accessible from anywhere else, but it'd
be very useful if it were.
Move it out into a `glue` crate, and make `tvix-cli` a consumer of it.
All the KnownPaths setup and passing around, as well as NIX_PATH
handling is also something that should probably be moved into the glue
crate as well, but that's something left for a future CL.

This makes magrathea use the repostory version of nix and git. This is
done in the pursuit of enforcing guaranteed unified experience of
magrathea tool across all users of a `tvl-kit`-based
repository. Especially among ubuntu users with uncontrolled set of
packages and versions installed on their system.
Not having this was giving build problems for `mg build` as one of the
users has 2.17 version of nix that had inconsistent hash computation
with 2.3.

builtins.intersectAttrs is used a _lot_ in nixpkgs eval, for whatever
reason. We previously had a very inefficient implementation that would
allocate for each comparison. It stuck out like a sore thumb in perf
analysis.
This moves to a custom algorithm with two iterators, one for the left
and one for the right side, advancing them along the (borrowed) map
keys until a match is found and allocation is required.
I've not made any effort to reduce the verbosity of this code, I don't
think it's worth it.
On my machine this reduces the mean runtime of evaluating
`nixpkgs.emacs.outPath` by ~8%.

As described in https://b.tvl.fyi/issues/313, the `nix_oracle` tests
currently fail if run without Nix 2.3 in `$PATH`.
This is not a problem for people running Nix 2.3 on their systems, and
neither is it for the tests running inside Nix derivations itself (as we
hardcode Nix 2.3 there), but for interactive `cargo test` runs, either
using `mg shell //tvix:shell`, or `nix-shell` (from the tvix workspace)
it currently is broken.
Adding Nix 2.3 to the shell fixes that.

The comment about what fixes have been applied was outdated (more was

Switch to there, which will also give us support for zstd, which was

The purpose of black_box is to actually prevent the compiler from being

To accomplish this, we need to actually *use* black_box to blackbox the

This incorporates the changes proposed in https://cl.tvl.fyi/9888 and
https://cl.tvl.fyi/9889, but by fixing it in crate2nix, and using the
(re-)generated version of it.
Changes were sent upstream at

this pulls in a minimal patch for now.

Replace morph with a 3 line bash script, which assumes your ssh_config
