[PATCH v2] .clang-format: introduce the use of clang-format

[Ramkumar Ramachandra <artagnon@gmail.com>]

Instead of manually eyeballing style in reviews, just ask all
contributors to run their patches through [git-]clang-format.

However, struct declarations that are combined with variable
declaration and initialization get mangled:

        struct a {
                int n;
                const char *s;
        } arr[] = {
                { 1, "one" },
                { 2, "two" }
        };

becomes:

        struct a {
                int n;
                const char *s;
        } arr[] = { { 1, "one" }, { 2, "two" } };

It gets formatted better if arr is declared separately.
