e4d6d20aa7 test(tvix/glue): add nonexisting_path_without_import test
This moves the failing example from cl/10285 into its separate test
case.

There were multiple complications: tvix-[ca]store was panicking in some
places, rather than returning an error. This is now fixed.

It needs to live in tvix-glue, so we actually have a "proper" EvalIO
interface doing something.

> toString ({ line = 42; col = 42; file = /deep/thought; }.file)

Should not cause an error, because it shouldn't trigger an import, but
leave the path as-is, and not care about it not being present.

7165ebc43b fix(tvix/eval): remove incorrect imports when coercing
The default behavior of string coercion in C++ Nix is to weakly coerce
and import to store if necessary. There is a flag to make it strongly
coerce (coerceMore) and a flag that controls whether path values have
the corresponding file/directory imported into the store before
returning the (store) path as a string (copyToStore). We need to
implement our equivalent to the copyToStore (import_paths) flag for the
benefit of weak coercions that don't import into the store (dirOf,
baseNameOf, readFile, ...) and strong coercions that don't import into
the store (toString).

This makes coerce_to_string as well as CoercionKind weirder and more
versatile, but prevents us from reimplementing parts of the coercion
logic constantly as can be seen in the case of baseNameOf.

Note that it is not possible to test this properly in //tvix/eval tests
due to the lack of an appropriate EvalIO implementation being available.
Tests should be added to //tvix/glue down the line.

3cdde8ad5a feat(tvix/glue): add some import tests
This creates a directory with a .keep file inside, and uses
"${path/to/there}" to coerce it to a string (and import it into the
store), ensuring it calculates the same store paths as Nix does.

07ca556a94 feat(tvix/glue): make unimplemented-structuredAttrs catchable
This commit adjusts the error produced by STRUCTURED_ATTRS so that
it is catchable.  This way we are able to enumerate the release
packageset, and the enumeration process will simply treat the few
derivations using structured attributes as being broken, rather than
killing the whole eval session.

8018313b68 feat(tvix/glue): add nixpkgs eval benchmark
This adds a criterion.rs-based testbench into tvix-glue.

It can be invoked by running `cargo bench` from inside the `tvix-glue`
crate.
`target/criterion/report/index.html` contains nice graphs.
It's able to diff against the previous run, so you can invoke `cargo
bench` before and after a certain change to reason about the impact in
evaluation performance.

Currently, we need to create a bunch of Evaluator resources inside the
benchmark loop itself, which is a bit annoying, as it leaks into the
things we benchmark.

This should become better with b/262.

Fixes b/322.

2b4920c355 fix(tvix/cli): panic on root cause of the fetchurl(non-boot) bug
Currently we produce wrong drvPaths for a large number of packages
that use fetchurl (but not fetchurlBoot, which is what stdenv uses).
A simple reproducer is `pkgs.perl538`.

I debugged this down to the root cause, which is the fact that tvix
doesn't realize that the mapping from FOD-paths to outputHash is
*NOT* a 1:1 mapping.  It is a many-to-one mapping.  You can have
lots of different FODs with the same outputHash or even the same
outPath.  For example, perl538.src and perldevel.src use the same
source tarball but a different `version`.

Anyways, I have found the root cause but have run out of time for a
while, so I've added a panic!() to in the spot where we have a logic
bug in order to call it out.

dfca879535 fix(tvix/glue): do not panic if PathInfoService returns Err
Nixpkgs tries to `import` the value returned by
`builtins.unsafeGetAttrPos`, which in our case is the file
`/deep/thought`.  Since that doesn't exist, tvix-glue panics, but
there's no interpreter backtrace to follow.

Let's return an Err instead of panicking.

3196fe0143 refactor(tvix): move tvix glue code into glue crate
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.
