ae98240df2 feat(gerrit): add code-owners plugin
This is the New Thing that is intended to replace the find-owners
and owners plugins.

In particular:

* It inserts a submit requirement rather than providing a Prolog
  predicate.
* The default OWNERS file formats are suspiciously Googley.
* It provides a neat UI for finding OWNERS and tracking approval
  state on a per-file basis.

When we fully migrate to using the code-owners plugin, a few
things will need to land, which I will likely do "offline"
directly to the Gerrit backing Git repos:

* Add the corresponding Gerrit config
* Replace OWNERS files depot-wide
* Add OWNERS files to the refs/meta/config branch
* Introduce the Owners-Override label, settable by depot-interventions

The enclosed patch adds two extra pieces of functionality that
we need in tvldepot but aren't upstream:

1. The ability to just specify usernames rather than email addresses
2. The ability to specify `group:GROUPNAME`, _as long as_ that group is
   visible to everyone. This is a restriction intended to avoid having
   the plugin just leak group membership.

b79e248959 refactor(tvix/eval): handle forcing in Builtin::apply
Instead of arity, we pass a array reference to Builtin::new that
describes how many arguments there are and which of them need to be
forced, eliminating the need to force manually.

Note that this change doesn't fix some of the instances where the the
Builtin doesn't consider that the value could be a Thunk.

to use Clap instead of doing things ad-hoc, and thread through options
obtained from environment variables via explicit arguments rather than
obtaining them from the environment as they're needed. This makes adding
more flags more sustainable, and also makes the binary fully
self-documenting, including supported env vars, via `--help`.

915ff5ac2a refactor(tvix/eval): Don't (ab)use PartialEq for Nix equality
Using rust's PartialEq trait to implement Nix equality semantics is
reasonably fraught with peril, both because the actual laws are
different than what nix expects, and (more importantly) because certain
things actually require extra context to compare for equality (for
example, thunks need to be forced). This converts the manual PartialEq
impl for Value (and all its descendants) to a *derived* PartialEq
impl (which requires a lot of extra PartialEq derives on miscellanious
other types within the codebase), and converts the previous
nix-semantics equality comparison into a new `nix_eq` method. This
returns an EvalResult, even though it can't currently return an error,
to allow it to fail when eg forcing thunks (which it will do soon).

Since the PartialEq impls for Value and NixAttrs are now quite boring,
this converts the generated proptests for those into handwritten ones
that cover `nix_eq` instead

0e5baae7ad refactor(tvix/eval): clone the Arc<codemap::File> for the compiler
This disconnects ownership of the `File` reference in a compiler from
the calling scope, which is required for when we implement `import`.

`import` will need to carry an `Rc<RefCell<CodeMap>>` (or maybe, in
the future, Arc) to give us the ability to add new detected code
files at runtime.

Note that the choice of `Arc` over `Rc` here is not ours - it's the
codemap crate's.

f8b3806720 test(tvix/eval): impl Arbitrary for Value
Impl Arbitrary for Value (and NixAttrs and NixList) in the same way we
did for NixString. Value currently only generates non-"internal"
values (no thunks, AttrNotFound, etc.) and can't generate
functions (builtins or closures), because those'd require full
generation of tvix bytecode, which is a bit more work than I'd like to
do now - there's a `todo!` left in the code for a place where we could
allow opting-in to internal values and functions later.

67e796b2e1 test(tvix/eval): Add the start of a nix oracle test suite
Add the start of a test suite that compares tvix eval results against
nix, using the string repr of the value as the comparison. This shells
out to a nix-instantiate binary, which is configurable as an environment
variable, to eval - there's some extra machinery there to setup a new
nix store as a tempdir to allow running this test inside the nix build
for tvix-eval itself.

Currently this has a macro that'll allow writing lots and lots of
hardcoded tests, but going forward I'm also going to be looking into
adding proptest-based generation of expressions to compare.

337d670d0c feat(tvix/eval): introduce ToSpan trait in compiler module
This trait can be used to convert most structures from rnix-parser
into a codemap::Span. It uses a macro to implement the trait for the
various expression types in the rnix AST, as Rust's silly semantic
versioning restriction stops us from doing a blanket implementation.

This will be used in the next commit to clean up the span handling in
the compiler a bit.

20230e1e2d feat(tvix/eval): implement recursive attribute sets
Yep.

This is kind of ugly right now. The idea is that the recursive_scope
compilation function is used for recursive sets as well by emitting
the keys. The rest of the logic is pretty much identical.

There is quite a lot of code here that can be cleaned up (duplication
between attrs and let, duplication inside of the recursive scope
compilation function etc.), but I'd like to get it working first and
then make it nice.

Note that nested keys are *not* supported yet.

a7e280ec00 refactor(tvix/eval): introduce a type for tracking bindings
This type is used in the list temporarily populated by the *second*
pass over all identifiers in a recursive scope. This first pass only
serves to make all bindings known to the compiler, without populating
their values yet.

Having a type here is going to be useful once we implement `rec`,
which needs to thread through slightly more information.
