V1 Docker ID <-> V2 layer SHA mismatch fix

Browse source 
Fix handling of V1 Docker ID <-> V2 layer SHA mismatch by dynamically rewriting the manifest to use new synthesized IDs for all layers above the mismatch. Also adds a bunch of tests for this and other use cases, fixes a bug around manifest digest uniqueness and fixes the 5.5 migration for MySQL.
