Code refactoring should've been a separate PR since I haven't found a way to "view changes from all commits except some specific commits in the middle of the list".

The codestyle change for C++ codebase is questionable because it looks too harsh on the eyes, makes the identifiers longer and steers naming convention from "object-properties-and-role-in-name" to "description-of-the-action-of-the-object", which becomes evident when you compare C codestyle to C++ codestyle.

Codestyle changes for Python looks reasonable but I'm not a python dev to comment on this. Again, it should've been a separate PR with different reviewers

As of build system changes and docs, I've left some comments that I think are critical.
