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.

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.

2022-11-23 r/5301 feat(tvix/eval): make NixList::clone() cheapAdam Joseph3-38/+36
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.

2022-11-21 r/5299 fix(tvix/eval): aggressively fix a borrow error in nix_eqVincent Ambo1-3/+9
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).

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.

2022-11-08 r/5271 chore(tvix/proto/castore.proto): rename link to symlinksFlorian Klink1-5/+5
Make it clear these are symlinks, not hardlinks. The term "link" is too heavily correlated to other meanings in IPFS/IPLD world, and calling this symlink removes this confusion.

2022-11-08 r/5269 feat(tvix/eval): Add docstrings as documentation for builtinsGriffin Smith5-2/+54
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.

2022-11-08 r/5268 feat(tvix/eval): Give names to builtin argumentsGriffin Smith6-57/+111
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.

2022-11-08 r/5267 refactor(tvix/eval): Be clearer about public interfaceGriffin Smith3-10/+16
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).
