This patch creates interfaces in builder/ for building Docker images. It is a first step in a series of patches to remove the daemon dependency on builder and later allow a client-side Dockerfile builder as well as potential builder plugins. It is needed because we cannot remove the /build API endpoint, so we need to keep the server-side Dockerfile builder, but we also want to reuse the same Dockerfile parser and evaluator for both server-side and client-side. builder/dockerfile/ and api/server/builder.go contain implementations of those interfaces as a refactoring of the current code.
