Closes #5529

i.e. without double pointer. With double pointer, it was possible to
submit `null` value, which will crash the server.

- replace `MaxReconnectAttempts`, `ReadWait`, `WriteWait` and `PingPeriod` options with `WSOptions` in `WSClient` (rpc/jsonrpc/client/ws_client.go).
- set default write wait to 10s for `WSClient`(rpc/jsonrpc/client/ws_client.go)
- unexpose `WSEvents`(rpc/client/http.go)

Closes #6162

```
// unbuffered
out, err := httpClient.Subscribe(ctx, "event.type=NewTx and account.name=Jack", 0)

// buffered
out, err := httpClient.Subscribe(ctx, "event.type=NewTx AND account.name=Jack", 20)
```

Before: when the `out` channel is buffered and becomes full, we drop an event (+ log the error)
After: when the `out` channel is buffered and becomes full, we block

**Before it was not apparent to the app when an event was dropped (looking at the logs is manual task). After this PR, if the user does not read from `out` on 1 subscription, all other subscriptions will be stuck too.**

Closes #6161

Closes #6155

Closes #6010

## Description

- removes blocktimeiota 
- merges block params in abci and core state
- spec change: https://github.com/tendermint/spec/pull/248


Closes: #5939

## Description

Separate protobuf and domain types. We should avoid using protobuf in our core logic. 

ref #5460

This test relied on connecting to the external site `foo-bar.net`, and (predictably) the site went down and broke all of our CI runs. This changes it to use local HTTP servers instead.

## Description

- bump gogoproto (1.3.2)
- regenerate proto files

Closes: #XXX

While debugging the mempool issue (#5796), I've noticed we're spending
quite a bit of time encoding blobs of data, which never get printed! The
reason is filtering occurs on the level below, so Go runtime rightfully
evaluates function arguments.

I think it's okay to not format raw bytes.

The `NodeInfo` interface does not appear to serve any purpose at all, so I removed it and renamed the `DefaultNodeInfo` struct to `NodeInfo` (including the Protobuf representations). Let me know if this is actually needed for anything.

Only the Protobuf rename is listed in the changelog, since we do not officially support API stability of the `p2p` package (according to `README.md`). The on-wire protocol remains compatible.

`abci.Client`:

- Sync and Async methods now accept a context for cancellation
    * grpc client uses context to cancel both Sync and Async requests
    * local client ignores context parameter
    * socket client uses context to cancel Sync requests and to drop Async requests before sending them if context was cancelled prior to that

- Async methods return an error
    * socket client returns an error immediately if queue is full for Async requests
    * local client always returns nil error
    * grpc client returns an error if context was cancelled before we got response or the receiving queue had a space for response (do not confuse with the sending queue from the socket client)

- specify clients semantics in [doc.go](https://raw.githubusercontent.com/tendermint/tendermint/27112fffa62276bc016d56741f686f0f77931748/abci/client/doc.go)

`mempool.TxInfo`

- add optional `Context` to `TxInfo`, which can be used to cancel `CheckTx` request

Closes #5190

## Description

In protobuf `[]byte` is varint encoded. When adding txs to the block we were not taking this into account.

Revert the JSON-RPC/WebSocket response serialization format to the
standard way (i.e. a single RPC response per WebSocket text message) to
avoid breaking clients.

Serialization format changes will be discussed in an upcoming ADR.

lost without any trace (log msg, etc.)

setting write buffer capacity to 1 makes transactions count per block
more stable and also reduces the pauses length by 20s.
