rpc: add support for batched requests/responses (#3534) Continues from #3280 in building support for batched requests/responses in the JSON RPC (as per issue #3213). * Add JSON RPC batching for client and server As per #3213, this adds support for [JSON RPC batch requests and responses](https://www.jsonrpc.org/specification#batch). * Add additional checks to ensure client responses are the same as results * Fix case where a notification is sent and no response is expected * Add test to check that JSON RPC notifications in a batch are left out in responses * Update CHANGELOG_PENDING.md * Update PR number now that PR has been created * Make errors start with lowercase letter * Refactor batch functionality to be standalone This refactors the batching functionality to rather act in a standalone way. In light of supporting concurrent goroutines making use of the same client, it would make sense to have batching functionality where one could create a batch of requests per goroutine and send that batch without interfering with a batch from another goroutine. * Add examples for simple and batch HTTP client usage * Check errors from writer and remove nolinter directives * Make error strings start with lowercase letter * Refactor examples to make them testable * Use safer deferred shutdown for example Tendermint test node * Recompose rpcClient interface from pre-existing interface components * Rename WaitGroup for brevity * Replace empty ID string with request ID * Remove extraneous test case * Convert first letter of errors.Wrap() messages to lowercase * Remove extraneous function parameter * Make variable declaration terse * Reorder WaitGroup.Done call to help prevent race conditions in the face of failure * Swap mutex to value representation and remove initialization * Restore empty JSONRPC string ID in response to prevent nil * Make JSONRPCBufferedRequest private * Revert PR hard link in CHANGELOG_PENDING * Add client ID for JSONRPCClient This adds code to automatically generate a randomized client ID for the JSONRPCClient, and adds a check of the IDs in the responses (if one was set in the requests). * Extract response ID validation into separate function * Remove extraneous comments * Reorder fields to indicate clearly which are protected by the mutex * Refactor for loop to remove indexing * Restructure and combine loop * Flatten conditional block for better readability * Make multi-variable declaration slightly more readable * Change for loop style * Compress error check statements * Make function description more generic to show that we support different protocols * Preallocate memory for request and result objects
