Naming and coding style convention, new linter tool. (#945)

* Makefile, Scripts: new linter * About: remove ID from IC * Firmware: remove double define for DIVC/DIVR * Scripts: check folder names too. Docker: replace syntax check with make lint. * Reformat Sources and Migrate to new file naming convention * Docker: symlink clang-format-12 to clang-format * Add coding style guide
