core, rpc: use Seek to iterate over NEP* transfers The results are controversial a bit. MemoryPS is a special storage and the new approach doesn't help it to iterate through NEP17 transfers. However, on long distances (if transfers are requested for more than 1000 blocks, which is ~4.1 hours of mainnet chain) both LevelDB and BoltDB perform good enough with the new approach. Taking into account the fact that default value for the query period of `getnep17transfers` RPC handler is a week (~40K mainnet blocks) we can sacrifice MemoryPS performance in favour of BoltDB and LevelDB optimisation.

core, rpc: use Seek to iterate over NEP* transfers The results are controversial a bit. MemoryPS is a special storage and the new approach doesn't help it to iterate through NEP17 transfers. However, on long distances (if transfers are requested for more than 1000 blocks, which is ~4.1 hours of mainnet chain) both LevelDB and BoltDB perform good enough with the new approach. Taking into account the fact that default value for the query period of `getnep17transfers` RPC handler is a week (~40K mainnet blocks) we can sacrifice MemoryPS performance in favour of BoltDB and LevelDB optimisation.

core: allow early Seek stop This simple approach allows to improve the performance of BoltDB and LevelDB in both terms of speed and allocations for retrieving GasPerVote value from the storage. MemoryPS's speed suffers a bit, but we don't use it for production environment. Part of #2322.

core: allow early Seek stop This simple approach allows to improve the performance of BoltDB and LevelDB in both terms of speed and allocations for retrieving GasPerVote value from the storage.
