C API: Fix bounds checking in _byidx functions
...
The docs weren't 100% clear about bounds checking, but suggested that
errors would be caught.
The bounds checks are cheap compared to the function calls they're in,
so we have no reason to omit them.

libexpr: Structural sharing of attrsets
...
This changes the implementation of Bindings to allow
for a more space-efficient implementation of attribute
set merges. This is accomplished by "layering" over the "base" Bindings.
The top "layer" is naturally the right-hand-side of the update operator //.
Such an implementation leads to significantly better memory usage on
something like nixpkgs:
nix-env --query --available --out-path --file ../nixpkgs --eval-system x86_64-linux > /dev/null

Make the JSON format for derivation use basename store paths
...
See #13570 for details --- the idea is that included the store dir in
store paths makes systematic JSON parting with e.g. Serde, Aeson,
nlohmann, or similiar harder.
After talking to Eelco, we are changing the `Derivation` format right
away because not only is `nix derivation` technically experimental, we think it is
also less widely used in practice than, say, `nix path-info`.
Progress on #13570

nix flake check: Skip substitutable derivations
...
Since `nix flake check` doesn't produce a `result` symlink, it doesn't
actually need to build/substitute derivations that are already known
to have succeeded, i.e. that are substitutable.
This can speed up CI jobs in cases where the derivations have already
been built by other jobs. For instance, a command like
nix flake check github:NixOS/hydra/aa62c7f7db31753f0cde690f8654dd1907fc0ce2
should no longer build anything because the outputs are already in
cache.nixos.org.

- Use `const K`, not `K`, otherwise we don't get auto referencing of

- Generalized the deleted overloads, because we don't care what the key
type is --- we want to get rid of anything that has an rvalue map
type.
