Update scripts have so far been built by concatenating all the historical changes and code from previous versions, leading to bloated update scripts, complicated script build process, and the need to keep old C-functions in compat.c since those functions are referenced during updates. This change greatly simplifies the way update scripts are built, significantly reducing the size of update scripts (to basically only the changeset + current code), and removing the need for compat.c. A few principles of building scripts must be followed going forward, as discussed in sql/updates/README.md.
