After final improvements to the official formatter implementation,
this commit now performs the first treewide reformat of Nix files using it.
This is part of the implementation of RFC 166.
Only "inactive" files are reformatted, meaning only files that
aren't being touched by any PR with activity in the past 2 months.
This is to avoid conflicts for PRs that might soon be merged.
Later we can do a full treewide reformat to get the rest,
which should not cause as many conflicts.
A CI check has already been running for some time to ensure that new and
already-formatted files are formatted, so the files being reformatted here
should also stay formatted.

# `dhallPackageToNix` is a utility function to take a Nixpkgs Dhall package
|
|
# (created with a function like `dhallPackages.buildDhallDirectoryPackage`)
|
|
# and read it in as a Nix expression.
|
|
#
|
|
# This function is similar to `dhallToNix`, but takes a Nixpkgs Dhall package
|
|
# as input instead of raw Dhall code.
|
|
#
|
|
# Note that this uses "import from derivation" (IFD), meaning that Nix will
|
|
# perform a build during the evaluation phase if you use this
|
|
# `dhallPackageToNix` utility. It is not possible to use `dhallPackageToNix`
|
|
# in Nixpkgs, since the Nixpkgs Hydra doesn't allow IFD.
