Use a base class to store the linker state since it is duplicated for every single part of the linker state.

Add base for ClusterKey; Rename PackageIdentifier to PackageKey; These both will only store a single integer as the key.

Add base for Dynamic and Dynamics which contains information that is only known at the final linking time.

Add Pool.require() which does not allow null entries on get; Add reading of this/super names and check validity.
