Use crates from parity-common: hashdb, keccak-hash, kvdb, kvdb-memorydb, kvdb-rocksdb, memorydb, parity-bytes, parity-crypto, path, patricia_trie, plain_hasher, rlp, target, test-support, trie-standardmap, triehash
The `patricia_trie` crate is generic over the hasher (by way of HashDB) and node encoding scheme. Adds a new `patricia_trie_ethereum` crate with concrete impls for Keccak/RLP.
