Add distribution package for managing pulls and pushes. This is based on the old code in the graph package, with major changes to work with the new image/layer model. Add v1 migration code. Update registry, api/*, and daemon packages to use the reference package's types where applicable. Update daemon package to use image/layer/tag stores instead of the graph package Signed-off-by: Aaron Lehmann <aaron.lehmann@docker.com> Signed-off-by: Tonis Tiigi <tonistiigi@gmail.com>
