util: add various helper functions to use __attribute__(cleanup) Taken from libei, with slight modifications. The general approach is: basic data types use _autofoo_ to call the maching foo function on cleanup. Struct types use _unref_, _destory_, _free_, whichever applies to that struct. Notably: attribute syntax depends on where it's declared [1] so in the following examles only a, b, and d have the autofree attribute: _autofree_ char a, b; char c, _autofree d; Simplest way to ensure it's all correct to keep the declarations one per line.

Add a clang-tidy file This gives us the ninja clang-tidy command. clang-tidy replaces scan-build and is more featureful (and picky).
