To minimally support wallets connected to pruned nodes, we add a new subsystem that can be integrated with chain clients to request blocks that the server has already pruned. This is done by connecting to the server's full node peers and querying them directly. Ideally, this is a capability supported by the server, though this is not yet possible with bitcoind.
