016993237f lib.callPackageWith: Optimize levenshtein sort
Probably not significant because of the limits already applied.
This is mostly cleanup.

67cc78643d lib.sortOn: init
A more efficient sort in some cases, and often convenient.

This exposes `lib.lists.sortOn` immediately on `lib`, because it is
a sibling of `sort`, which is already present there.
Omitting it would lead to more confusion, and worse outcomes.
There's no confusion about the types `sort` or `sortOn` operate on.

Haskell agrees about the type for `sortOn`, and it is in its `base`.

lib.systems.elaborate: fix passing rust (more) (#271707)
An important idea around the rust stuff in lib.systems is that it's
elaborated — this means that it should idempotently add to the values
passed in, if any.  But we missed that the names used for the
parameter and the elaborated value for "rustcTarget"/"config" didn't
line up.  The intention was to use "rustcTarget" everywhere in the new
interface, as a more descriptive name than "config".

This fixes setting the system in NixOS configuration, which results in
an already elaborated system being elaborated again.  Before, this
wouldn't produce the correct result:

% nix-instantiate --eval -A stdenv.hostPlatform.rust.rustcTarget --system armv7l-linux
"armv7-unknown-linux-gnueabihf"
% NIX_PATH= nix-instantiate --eval -E '(import nixos/lib/eval-config.nix { system = "armv7l-linux"; modules = []; }).pkgs.stdenv.hostPlatform.rust.rustcTarget'
"arm-unknown-linux-gnueabihf"

62f7a6dcc1 lib.systems.elaborate: fix passing rust
Usually, attributes passed explicitly to elaborate take precedence
over the elaborated ones, but since we also elaborate the nested
"rust" attrset, we need to push that one level down, so the rest of
"rust" is still filled in if you just pass
{ rust = { config = ... } }.

I've had to drop the assertion that checked that at most one of "rust"
and "rustc" was part of the un-elaborated system, because doing this
broke passing an elaborated system in, which should be idempotent.

For the same reason, I've also had to make it possible for
rust.rustcTargetSpec to be passed in.  Otherwise, on the second call,
since platform was filled in by the first, the custom target file
would be constructed.  The only other way to avoid this would be to
compare the platform attrs to all built in Rust targets to check it
wasn't one of those, and that isn't feasible.

54c9a08aaf lib.tests: build nix without flaky aws-sdk-cpp
The aws-sdk-cpp tests are flaky.

Since pull requests to staging cause nix to be rebuilt, this means
that staging PRs end up getting false CI failures due to whatever is
flaky in the AWS SDK tests.  Since none of our CI needs to (or
should be able to) contact AWS S3, let's just omit it all.  Bonus:
the tests build way faster.

1c3eb9eff1 lib.fileset.fileFilter: Restrict second argument to paths
While this change is backwards-incompatible, I think it's okay because:
- The `fileFilter` function is not yet in a stable NixOS release, it was only merged about [a month ago](https://github.com/NixOS/nixpkgs/pull/257356).
  - All public uses of the function on GitHub only pass a path
- Any `fileFilter pred fileset` can also be expressed as `intersection fileset (fileFilter pred path)` without loss of functionality.
  - This is furthermore pointed out in the new error message when a file set is passed
