Format all Nix files using the officially approved formatter,
making the CI check introduced in the previous commit succeed:
nix-build ci -A fmt.check
This is the next step of the of the [implementation](https://github.com/NixOS/nixfmt/issues/153)
of the accepted [RFC 166](https://github.com/NixOS/rfcs/pull/166).
This commit will lead to merge conflicts for a number of PRs,
up to an estimated ~1100 (~33%) among the PRs with activity in the past 2
months, but that should be lower than what it would be without the previous
[partial treewide format](https://github.com/NixOS/nixpkgs/pull/322537).
Merge conflicts caused by this commit can now automatically be resolved while rebasing using the
[auto-rebase script](8616af08d9/maintainers/scripts/auto-rebase).
If you run into any problems regarding any of this, please reach out to the
[formatting team](https://nixos.org/community/teams/formatting/) by
pinging @NixOS/nix-formatting.
work around for `ld: file not found: @rpath/libquadmath.0.dylib` which
occurs due to an mpi test linking with `-flat_namespace` can remove once
`-flat_namespace` is removed or

Copy darwin flags `-ff2c -fno-second-underscore` from workflow to use
Accelerate without segfaulting / failing tests and enable the Accelerate
framework when `useAccel` is true.

The arpack package included the eigen library and added it to the build
inputs but neglected to enable its use by setting `EIGEN=ON` in the
build flags. Enable support for eigenvalue-problems solver based on ICB
and eigen and disable parallel checking as the tests fail when run in
parallel.
Change 07cdea2ae5 uncovered a bug in how
we build arpack on darwin with the Accelerate. Disable the Accelerate
framework and use openblas the default nixpkgs blas/lapack
implementation.
We are migrating packages that meet below requirements:
1. using `callPackage`
2. called path is a directory
3. overriding set is empty (`{ }`)
4. not containing path expressions other than relative path (to
makenixpkgs-vet happy)
5. not referenced by nix files outside of the directory, other
than`pkgs/top-level/all-packages.nix`
6. not referencing nix files outside of the directory
7. not referencing `default.nix` (since it's changed to `package.nix`)
8. `outPath` doesn't change after migration
