Fix: Division by page size in NeedsGarbageCollection. Original description: Generalize the interface of page space controller. Gather used/capacity/external into SpaceUsage object, and use it for testing whether GC is needed before or after an allocation. This refactor does not affect policy, but prepares for: 1. Replacing promotion failure check/tracking. 2. Better growth control for external allocation.
