Need `.clang-format` or equivalent code style enforcement

[Jo3Zhou]

I don't like the standard glib/gtk formatting rule, any .clang-format or something similar would be great!

@Jo3Zhou Sort of the same as earlier answer. If you want it you need to make it ;)

Thanks for getting back so quickly. Do you think adding a new clang-format file will break the history?

[lundmar]

To be honest, it is very subjective what is good code formatting. If you make a .clang-format that results in touching formatting everywhere then it will sort of break git history.

I think .clang-format can be a good helper tool but in my experience they are hard to tune just right according to my own preferred formatting.
