This changes adds an `MempoolError` field to the `ResponseCheckTx`. This will allow clients to understand that their transaction was rejected from the mempool despite passing the ABCI check. This change also updates the code to make use of early returns to prevent highly nested code blocks. Namely, it returns when the type assertion fails at the beginning of the method, instead of wrapping the entire method in a large if statement. This has a somewhat large effect on the diff as rendered by github. addresses: #3546
Tendermint RPC
Pagination
Requests that return multiple items will be paginated to 30 items by default. You can specify further pages with the ?page parameter. You can also set a custom page size up to 100 with the ?per_page parameter.
Subscribing to events
The user can subscribe to events emitted by Tendermint, using /subscribe. If
the maximum number of clients is reached or the client has too many
subscriptions, an error will be returned. The subscription timeout is 5 sec.
Each subscription has a buffer to accommodate short bursts of events or some
slowness in clients. If the buffer gets full, the subscription will be canceled
("client is not pulling messages fast enough"). If Tendermint exits, all
subscriptions are canceled ("Tendermint exited"). The user can unsubscribe
using either /unsubscribe or /unsubscribe_all.
