various improvements

- pledge tools and add define to enable it on platforms that support it, currently
  only OpenBSD 5.9+
- separate getline and parseline functionality.
- use murmur3 hash instead of jenkins1: faster and less collisions.
- make some error messages a bit more clear, for example with path truncation.
- some small cleanups, move printutf8pad to util.
