core: add InitializeCache method to NEO native contracts There might be a case when cached contract values store nil (e.g. after restoring chain from dump). We should always initialize cached values irrespective to the (NEO).Initialize method.

core: add InitializeCache method to NEO native contracts There might be a case when cached contract values store nil (e.g. after restoring chain from dump). We should always initialize cached values irrespective to the (NEO).Initialize method. This commit fixes a bug introduced in 83e94d3 when 4-nodes privnet is failing after restoring from dump: ``` $ docker logs neo_go_node_one => Try to restore blocks before running node 2020-09-30T11:55:49.122Z INFO no storage version found! creating genesis block 2020-09-30T11:55:49.124Z INFO service hasn't started since it's disabled {"service": "Pprof"} 2020-09-30T11:55:49.124Z INFO service hasn't started since it's disabled {"service": "Prometheus"} 2020-09-30T11:55:49.124Z INFO skipped genesis block {"hash": "3792eaa22c196399a114666fd491c4b9ac52491d9abb1f633a8036a8ac81e4db"} 2020-09-30T11:55:49.141Z INFO shutting down service {"service": "Pprof", "endpoint": ":30001"} 2020-09-30T11:55:49.141Z INFO shutting down service {"service": "Prometheus", "endpoint": ":40001"} 2020-09-30T11:55:49.141Z INFO blockchain persist completed {"persistedBlocks": 3, "persistedKeys": 146, "headerHeight": 3, "blockHeight": 3, "took": "324.27µs"} 2020-09-30T11:55:49.150Z INFO restoring blockchain {"version": "0.1.0"} 2020-09-30T11:55:49.150Z INFO service hasn't started since it's disabled {"service": "Prometheus"} 2020-09-30T11:55:49.151Z INFO service hasn't started since it's disabled {"service": "Pprof"} 2020-09-30T11:55:49.443Z INFO starting rpc-server {"endpoint": ":30333"} 2020-09-30T11:55:49.443Z INFO node started {"blockHeight": 3, "headerHeight": 3} _ ____________ __________ / | / / ____/ __ \ / ____/ __ \ / |/ / __/ / / / /_____/ / __/ / / / / /| / /___/ /_/ /_____/ /_/ / /_/ / /_/ |_/_____/\____/ \____/\____/ /NEO-GO:/ 2020-09-30T11:55:49.444Z INFO new peer connected {"addr": "172.23.0.5:39638", "peerCount": 1} 2020-09-30T11:55:49.444Z INFO new peer connected {"addr": "172.23.0.5:20333", "peerCount": 2} 2020-09-30T11:55:49.444Z WARN peer disconnected {"addr": "172.23.0.5:20333", "reason": "identical node id", "peerCount": 1} 2020-09-30T11:55:49.445Z WARN peer disconnected {"addr": "172.23.0.5:39638", "reason": "identical node id", "peerCount": 0} 2020-09-30T11:55:49.445Z INFO new peer connected {"addr": "172.23.0.3:20335", "peerCount": 1} 2020-09-30T11:55:49.445Z INFO new peer connected {"addr": "172.23.0.2:20334", "peerCount": 2} 2020-09-30T11:55:49.445Z INFO started protocol {"addr": "172.23.0.3:20335", "userAgent": "/NEO-GO:/", "startHeight": 3, "id": 1339919829} 2020-09-30T11:55:49.445Z INFO new peer connected {"addr": "172.23.0.4:20336", "peerCount": 3} 2020-09-30T11:55:49.445Z INFO started protocol {"addr": "172.23.0.4:20336", "userAgent": "/NEO-GO:/", "startHeight": 3, "id": 4036722359} 2020-09-30T11:55:49.445Z INFO node reached synchronized state, starting consensus 2020-09-30T11:55:49.445Z INFO started protocol {"addr": "172.23.0.2:20334", "userAgent": "/NEO-GO:/", "startHeight": 3, "id": 1557367037} panic: runtime error: integer divide by zero goroutine 132 [running]: github.com/nspcc-dev/dbft.(*Context).GetPrimaryIndex(...) github.com/nspcc-dev/dbft@v0.0.0-20200925163137-8f3b9ab3b720/context.go:83 github.com/nspcc-dev/dbft.(*Context).reset(0xc0000e0780, 0x0) github.com/nspcc-dev/dbft@v0.0.0-20200925163137-8f3b9ab3b720/context.go:208 +0x64b github.com/nspcc-dev/dbft.(*DBFT).InitializeConsensus(0xc0000e0780, 0x964800) github.com/nspcc-dev/dbft@v0.0.0-20200925163137-8f3b9ab3b720/dbft.go:87 +0x51 github.com/nspcc-dev/dbft.(*DBFT).Start(0xc0000e0780) github.com/nspcc-dev/dbft@v0.0.0-20200925163137-8f3b9ab3b720/dbft.go:81 +0x4b github.com/nspcc-dev/neo-go/pkg/consensus.(*service).Start(0xc0001a2160) github.com/nspcc-dev/neo-go/pkg/consensus/consensus.go:206 +0x56 github.com/nspcc-dev/neo-go/pkg/network.(*Server).tryStartConsensus(0xc0000ec500) github.com/nspcc-dev/neo-go/pkg/network/server.go:311 +0xda github.com/nspcc-dev/neo-go/pkg/network.(*Server).handleMessage(0xc0000ec500, 0x104d800, 0xc000222090, 0xc0000a6f10, 0x0, 0x0) github.com/nspcc-dev/neo-go/pkg/network/server.go:781 +0xa7a github.com/nspcc-dev/neo-go/pkg/network.(*TCPPeer).handleConn(0xc000222090) github.com/nspcc-dev/neo-go/pkg/network/tcp_peer.go:162 +0x2e7 created by github.com/nspcc-dev/neo-go/pkg/network.(*TCPTransport).Dial github.com/nspcc-dev/neo-go/pkg/network/tcp_transport.go:40 +0x1ac ```

native: optimize gas per vote calculation GAS per vote records are being returned from Seek in ascending way, and we need the last record before the specified index which is close to the current chain's height (most of the time).

native: optimize gas per vote calculation GAS per vote records are being returned from Seek in ascending way, and we need the last record before the specified index which is close to the current chain's height (most of the time). To optimize we can iterate backwards strting from the last record using SeekBackwards. name old time/op new time/op delta NEO_GetGASPerVote/MemPS_10RewardRecords_1RewardDistance-8 27.7µs ± 8% 30.3µs ±
