Subject: build: allow packages to declare ABI versions to detect necessary
package rebuilds
If a package directly depends on another package that recently changed
its ABI version, it will be cleaned up and rebuilt (assuming quilt is
not used).
This helps with packages that have no stable ABI, e.g. libubox, ubus,
etc.
