Epic: line/lbm#1263
Cherry-pick: #49, #51
Description
To optimize performance, we need to increase concurrency. As a first step for it, I implement concurrent checkTx. The key change is to remove app.mtx.Lock() from the abci local client. An application, as an abci server, is better to protect itself from concurrency than an abci client. W/ current implementation, the abci local client protects an abci server but it decreases concurrency.
CONTRACT:
Now, an application should protect itself from concurrent checkTx as an abci server that means it should be thread safe.
We'll also increase concurrency for other abci methods as much as possible in the future.
