finally introduce .clang-format; request for comments and changes

psi29arequested to merge
clangformat into master

To help developers, current and future, to keep a consistent style, I propose a project-wide style guideline.

Exemption: everything on /extern since we don't want to stray too far from upstream

This is a RFC (request for comments), if you feel like it can be changed or should be changed, you are more than welcome to edit this MR directly or create a MR to adapt it.
