feat: format the code with clang-format
The code currently mixes tab and space indenting. Having the code style defined into a file is usually good practice, as we can use tools to do it automatically. This change proposes use clang-format to do it. It provides predefined rules following LLVM/Google/Mozilla/GNU code style that can be tweaked. I try to create a .clang-format configuration that just fix the tab/space mix and keep the rest as-is as much I can. Currently all cpp/hpp/h are formatted except those in src/ext. The code formatting will be checked Jenkins. It also can be run with: `cmake .. && make clang-format` cmake also install automatically a pre-commit hook to format the code. It can be disabled with `INSTALL_GIT_HOOKS=OFF` llvm provide some basic integration for editor: https://clang.llvm.org/docs/ClangFormat.html#vim-integration https://clang.llvm.org/docs/ClangFormat.html#emacs-integration But you can also use other tools like: https://github.com/SavchenkoValeriy/emacs-clang-format-plus
