Ethash cannot cache more than 1 verification DAG. This causes issues when doing epoch transitions, since uncles and block headers might be in different epochs, and further parallel PoW checks could hamper the internal cache of ethash.
This PR adds a caching layer in front of ethash, which uses 3 (geth import) / 5 (normal operation) ethash instances to verify PoWs, always replacing the oldest used cache whenever one is needed for a new cache.
