This PR finishes implementing warp syncing for the full node.
The full node now starts by performing a warp sync. Once finished, it immediately starts syncing new blocks. If the database doesn't contain enough information to sync new blocks, a call proof is downloaded from the network.
In parallel of syncing new blocks, the missing storage items of new blocks are downloaded.
There seems to be quite a few bugs at the moment, but I'm going to merge this PR anyway in order to unlock further changes such as removing the optimistic syncing.
