* pre-commit: Update and enable clang-format check There is newer version from clang-format so use that. We do not yet want 18 as that is little bit too new. * Format some thing by hand which clang-format "breaks" Clang-format will format some things little bit off in some cases. Format some things by hand so we get cleaner end result. * Run clang-format with ``` pre-commit run --all-files clang-format ``` We have already in previously checked places where clang-format does not make good format and ignored those (hopefully most of the things). --------- Co-authored-by: Kari Argillander <kari.argillander@fidelix.com>
