f282984c25 fix(tvix/eval): use rnix-parser from crates.io
A few weeks ago, oberblastmeister did a release to crates.io so we can
stop importing it via GitHub.

f4e17caae8 feat(tvix/eval): Continue removing leakage of BTreeMap.
Fixes b/212. Based on feedback in https://cl.tvl.fyi/c/depot/+/7492, all
uses of `NixAttrs::from_map` have been removed. Only `from_iter` and
`from_kv` remain.

39dba6aa16 feat(tvix/eval): impl FromIterator for NixAttrs
Allows for the removal of some BTreeMap usage when constructing NixAttrs
by allowing any iterator over 2-tuples to build a NixAttrs. Some
instances of BTreeMap didn't have anything to do with making NixAttrs,
and some were just the best tool for the job, so they are left using the
old `from_map` interface.

90fe9a51d7 test(tvix/eval): check inner forcing despite declaring pointer
Maybe counter-intuitively the inner elements of a list or the
attribute values of an attribute set will be forced despite
pointer equality (but only one layer deep).

56c00df710 feat(tvix/eval): use backtrace-on-stack-overflow crate
The backtrace-on-stack-overflow create provides best-effort stack
traces when a stack overflow happens.  Since it's running on the
(usually tiny) signal alternate stack this isn't easy.

This is guarded by a new `backtrace_overflow` feature flag and never
enabled (even if that feature is selected) for release builds.  This
is strictly for debugging; there's crazy unsafe voodoo in there.

   https://lib.rs/crates/backtrace-on-stack-overflow

Example output:

325a7d6fa9 test(tvix/eval): add eval-okay-closure-pointer-compare
This test case checks two things:

* A sanity check that "pointer equality for functions" means not
  just the lambda, but also the upvalues.

* To be pointer-equal, it is not enough for the upvalues to be
  normal-form equal (i.e. `nix_eq()`-equal); the upvalues must be
  *pointer*-equal.  The second part of the test case checks for
  this.

11874d3a71 chore(tvix/eval): postpone use of "dep:" for a bit
The "dep:" syntax in Cargo.toml is very new; crate2nix master has
support for it, but they have not yet made a release with this
update, and therefore the crate2nix in nixpkgs does not yet support
it.

Could we avoid using "dep:" for a few weeks to give crate2nix a
chance to release so I can bump the version in nixpkgs?  I've opened
an issue asking crate2nix to make a release:

  https://github.com/kolloch/crate2nix/issues/264

I propose that if they haven't acted within a month we stop waiting
and revert this at that time.

a740653c83 feat(tvix/eval): make NixList::clone() cheap
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.

878dc6c227 fix(tvix/eval): aggressively fix a borrow error in nix_eq
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).

e1e8285ecf test(tvix/eval): enable eval-okay-closure test from nix_tests
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).

ae30def055 feat(tvix/eval): Implement builtins.genericClosure
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.

This commit was written somewhere in the North Sea.

76d7671c8a feat(tvix/eval): Add docstrings as documentation for builtins
Add a new `documentation: Option<&'static str>` field to Builtin, and
populate it in the `#[builtins]` macro with the docstring of the builtin
function, if any.

a1015ba1d7 feat(tvix/eval): Give names to builtin arguments
Refactor the arguments of a Builtin to be a vec of a new BuiltinArgument
struct, which contains the old strictness boolean and also a static
`name` str - this is automatically determined via the ident for the
corresponding function argument in the proc-macro case, and passed in in
the cases where we're still manually calling Builtin::new.

Currently this name is unused, but in the future this can be used as
part of a documentation system for builtins.

dad07a8bc0 refactor(tvix/eval): Be clearer about public interface
Some new top-level re-exports (specifically VM, Builtin, and ErrorKind)
were added to lib.rs in tvix/eval to allow the builtin-macros tests to
work - we should be clear which of these are part of the public
interface (I think it's reasonable for ErrorKind to be) and which
aren't (specifically I'm not sure VM and Builtin necessarily should be,
at least yet).

a4c9cc8d5e refactor(tvix/eval): Define impure builtins using the macro
Similar to what we did with pure builtins, define the impure builtins
within a module at the top-level using the new #[builtins] attribute

43eb4900e0 refactor(tvix/eval): Define a single builtin at the top level
Mostly as a proof-of-concept of the new proc-macros for defining
builtins, define a single builtin (the first in the list, `abort`) at
the top-level of a child module within builtins/mod.rs, and add it to
the list of builtins returned from `pure_builtins`.

If this works nicely, we can start breaking out the rest of the builtins
into the top-level too, in addition to introducing additional sets of
builtins (to differentiate between pure and impure builtins).

645d0c06e5 feat(tvix/eval): Add a proc-macro for defining builtins
Add a single new proc macro to a new proc-macro crate,
`tvix-eval-proc-macros` for defining an inline module containing nix
builtins, and automatically generating a function within that module
which returns a list of those builtins as `tvix_eval::value::Builtin`.
