tx indexing (Refs #237)
save transactions to blockstore move to a separate module benchmark KVIndexer batch write transactions Benchmarks: ``` BenchmarkKVIndexerIndex-2 100000 516300 ns/op PASS ok github.com/tendermint/tendermint/blockchain/tx 56.506s 5,16 s for 10000 transactions 1 s for 2000 transactions ``` ``` BenchmarkKVIndexerIndex-2 h 3000000 8622 ns/op PASS ok github.com/tendermint/tendermint/blockchain/tx 34.210s 86 ms for 10000 transactions 16 ms for 2000 transactions ``` ``` BenchmarkKVIndexerIndex1-2 5000000 7160 ns/op BenchmarkKVIndexerIndex500-2 20000 1750411 ns/op BenchmarkKVIndexerIndex1000-2 10000 3573973 ns/op BenchmarkKVIndexerIndex2000-2 5000 7836851 ns/op BenchmarkKVIndexerIndex10000-2 1000 33438980 ns/op PASS ok github.com/tendermint/tendermint/blockchain/tx 209.482s 7,8 ms for 2000 transactions ``` [state] write test for ApplyBlock review comments - move txindexer to state - fix type save Tx Index as well do not store tx itself in the result
