Robert Hensing fbf5fab083 feat(nix-bindings-expr): add RecoverableError for non-memoized primop errors

Nix 2.34 memoizes primop errors by default. RecoverableError uses
NIX_ERR_RECOVERABLE so transient errors allow the thunk to be retried.

Unreleased

primop::RecoverableError for primop errors that should not be memoized in the thunk, allowing retry on next force. Required by Nix >= 2.34 (release note) for recoverable errors to remain recoverable, as Nix 2.34 memoizes errors by default.

Workaround for automatic C library input propagation in downstream Nix builds. (#27 by @roberth)
EvalStateBuilder::load_ambient_settings() to control whether global Nix settings are loaded. (#36 by @roberth)

Path coercion failing with "path does not exist" errors due to missing eval_state_builder_load() call. (#36 by @aanderse)

Split nix-bindings-util-sys (which contained all low-level FFI bindings) into separate per-library *-sys crates. (#27 by @Ericson2314) This allows downstream crates to depend on just the low-level bindings they need without pulling in higher-level crates.

Initial release, extracted from the nixops4 repository.
