* Update rules_haskell: Generates version macros
- rules_haskell now generates a version macros header file that is
passed on to preprocessors such as c2hs or hsc2hs.
- The haskell_import rule was also renamed to haskell_toolchain_library.
* Drop unix-compat patch
This was necessary to work around missing version macros.
* Add buildifier targets.
The tool allows to check and format BUILD files in the repo.
To check if files are well formatted, run:
bazel run //:buildifier
To fix badly-formatted files run:
bazel run //:buildifier-fix
* Cleanup dade-copyright-headers formatting.
* Fix dade-copyright-headers on files with just the copyright.
* Run buildifier automatically on CI via 'fmt.sh'.
* Reformat all BUILD files with buildifier.
Excludes autogenerated Bazel files.
