2023-10-28 r/6902 fix(nix-compat/narinfo): don't allocate errors earlyedef1-11/+12
We also switch the MissingField error to &'static str, since we only parse a fixed set of fields. Together, this makes the performance impact of error handling negligible in batch happy-path parsing.

2023-10-23 r/6871 refactor(tvix/nix-compat): rename NixHashWithMode -> CAHashFlorian Klink9-204/+217
This specific struct is only used to represent content-addressed paths (in case a Derivation has a fixed-output hash, for example). Rename `Output`'s `hash_with_mode` to `ca_hash`. We now also include `CAHash::Text`, and update the `validate` function of the `Output` struct to reject text hashes there. This allows cleaning up the various output path calculation functions inside nix-compat/src/store_path/utils.rs, as they can now match on the type. `make_type` is renamed to `make_references_string`, `build_regular_ca_path` is renamed to `build_ca_path`, and `build_text_path` has a disclaimer added, because you might not actually want to use it.

Some of the lower-level ATerm primitives are moved into a (new) aterm module, and some more higher-level ones that construct derivation- specific types. Also, move the escape_bytes function into there, this is a generic ATerm thing.
