* use namespace::subnamespace where applicable * make minio::error::SUCCESS declared only once * make more constructors explicit (minio::error) * moved constants that seem private into .cc files * added .clang-format file to enforce more formatting rules Co-authored-by: Petr Kobalicek <petr.kobalicek@min.io>
