2023-01-12 r/5652 feat(tvix/eval): implement builtins.toJSONVincent Ambo11-10/+75
Implements `Serialize` for `tvix_eval::Value`. Special care is taken with serialisation of attribute sets, and forcing of thunks. The tests should cover both cases well.

2023-01-11 r/5643 feat(tvix/cli): implement initial refscan moduleVincent Ambo5-0/+104
This module implements a ReferenceScanner struct which uses the aho_corasick crate to scan string inputs for known, non-overlapping candidates (store paths, in our case). I experimented with several different APIs, and landed on this version with an initial accumulator in the scanner. The scanner is instantiated from the candidates and "fed" all the strings, then consumed by the caller to retrieve the result. Right now only things that look vaguely like bytestrings can be fed to the scanner, there is no streaming support in the API yet.

packed_simd is deprecated, but we don't need very much SIMD: * _mm256_set1_epi8 / vpbroadcastb (splat) * _mm256_cmpgt_epi8 / vpcmpgtb (comparison) * _mm256_movemask_epi8 / vpmovmskb (compress to bitmask) This also simplifies the code by only vectorising the bare minimum, since we just get a bitmask and operate in scalar mode as soon as possible. We don't need nightly Rust anymore: we're using only stable intrinsics.

A simple categorical parser that does not implement Monad, and does not contain an `m` and some rudementary error message handling. In the future I’d probably want to wrap everything in an additional `m`, so that subparsers can somehow use `Selective` to throw errors from within `m` that contain the parsing context if at all possible. Hard to do without Monad, I have to say. Not even stuff like `StateT` works without the inner `m` implementing `Monad`.
