Summarizing input from François: Look into integrating a trait-based crate for tracking heap memory usage, perhaps: 1. https://github.com/paritytech/parity-common/tree/master/parity-util-mem 2. https://github.com/Aeledfyr/deepsize/ Validate the approach by carefully instrumenting a set of types...

Also deletes the notion of `AvailabilityResponse` and `RequestID` from `BlockSynchronizer`.
