[PATCH 0/8] clang-format: add more rules and enable on CI

[Karthik Nayak <karthik.188@gmail.com>]

The series was mostly inspired by a patch sent recently to 'include
kh_foreach* macros in ForEachMacros' [1]. I was wondering why we don't
run the formatting on CI and reduce some of the workload of reviewers.

We have a '.clang-format' file to provide rules for code formatting.
The commits 1-6 aims to add more rules to the file while deprecating old
ones.

Commit 7 enables CI action on GitHub and GitLab to also check for the
code formatting. Currently, it is allowed to fail. This way we can build
confidence and fine tune the values as needed and finally enforce the
check in a future patch. I'm not well versed with GitHub workflows, and
I mostly tried to copy existing work there. Expecting some feedback in
that section!

Commit 8 fixes an existing issue with the 'check-whitespace' job, which
is failing as success in the GitLab CI.
