Closes https://github.com/tendermint/tendermint/issues/3857 Moves `lib/` folder to `jsonrpc/`. Renames: **packages** `rpc` package -> `jsonrpc` package `rpcclient` package -> `client` package `rpcserver` package -> `server` package **structs and interfaces** ``` JSONRPCClient to Client JSONRPCRequestBatch to RequestBatch JSONRPCCaller to Caller ``` **functions** ``` StartHTTPServer to Serve StartHTTPAndTLSServer to ServeTLS rpc/jsonrpc/client: rename NewURIClient to NewURI NewJSONRPCClient to New NewJSONRPCClientWithHTTPClient to NewWithHTTPClient NewWSClient to NewWS ``` **misc** - unexpose `ResponseWriterWrapper` - remove unused http_params.go
