Remove `Context` from the `TxInfo` type and instead require the caller to pass a `Context` to `CheckTx` which is idiomatic.

By pre-creating the hasher, instead of creating new one everytime
addrbook.hash is called.

Addresses a beginning component of #6255

## Description

Add version back to versions, but allow it to be overridden via a ldflag.

Reason:

Many users are not setting the ldflag causing issues with tooling that relies on it (cosmjs)

Adds `block_id` to the `newblock` websocket event

Closes #6028

## Description

Internalize some libs. This reduces the amount ot public API tendermint is supporting. The moved libraries are mainly ones that are used within Tendermint-core.

So we can reduce pressure on runtime for checking that slice has enough
capacity before appending.

## Description

Add sr25519 as a validator key option. We support the crypto in tendermint and added batch verification recently.

I believe that this, in my testing seems to help the e2e state-sync
tests complete more reliably, by fixing some potential, range-related
slice building, as well as the way the test app hashes snapshots.

Additionally, and I'm not sure if we want to do this, but I added this
hook to the reactor that re-sends the request for snapshots during the
retry. This helps in tests prevent systems from getting stuck, but I
think in reality, it might create more traffic, and operators would
just restart a state-syncing node to get a similar effect.

## Description

- Add `context.Context` to Privval interface

This pr does not introduce context into our custom privval connection protocol because this will be removed in the next release. When this pr is released.

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

## Description

- return errors on `loadFilePv`

closes #6182

Closes #6146

also

- 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

Fixes the race condition between a callback being set and called during ReCheckTx. Note, I do not see equivalent logic in the gRPC client (anymore) as #5439 suggests, so only the socket client was updated.

closes: #5439

## Description

- remove unused functions
- remove a function used in tests.

Closes: #XXX
