Selection of improvements for best practices and avoiding big memory allocations in init stage in places where it doesn't degrade readability. For benchmarks this doesn't make a giant difference overall as bigger issues are in some of the dependencies, but need to start somewhere. This is mostly preparation for some other updates and for defining standards for future changes. All regexp.Compile issues were skipped for now but the detection logic is in https://gist.github.com/tonistiigi/1d58b4c2de41d194f35ac2c9f029f586 . Validations like this should be eventually integrated into CI.
