The responses from node RPCs encode hash values as hexadecimal strings. This
behaviour is stipulated in our OpenAPI documentation. In some cases, however,
hashes received as JSON parameters were being decoded as byte buffers, as is
the convention for JSON.

This resulted in the confusing situation that a hash reported by one request
(e.g., broadcast_tx_commit) could not be passed as a parameter to another
(e.g., tx) via JSON, without translating the hex-encoded output hash into the
base64 encoding used by JSON for opaque bytes.

Fixes #6802.

EDIT: Updated, see [comment below]( https://github.com/tendermint/tendermint/pull/6785#issuecomment-897793175)

This change adds a sketch of the `Debug` mode. 

This change adds a `Debug` struct to the node package. This `Debug` struct is intended to be created and started by a command in the `cmd` directory. The `Debug` struct runs the RPC server on the data directories: both the state store and the block store.

This change required a good deal of refactoring. Namely, a new `rpc.go` file was added to the `node` package. This file encapsulates functions for starting RPC servers used by nodes. A potential additional change is to further factor this code into shared code _in_ the `rpc` package. 

Minor API tweaks were also made that seemed appropriate such as the mechanism for fetching routes from the `rpc/core` package.

Additional work is required to register the `Debug` service as a command in the `cmd` directory but I am looking for feedback on if this direction seems appropriate before diving much further.

closes: #5908

This change aims to keep versions of mockery consistent across developer laptops.

This change adds mockery to the `tools.go` file so that its version can be managed consistently in the `go.mod` file.

Additionally, this change temporarily disables adding mockery's version number to generated files. There is an outstanding issue against the mockery project related to the version string behavior when running from `go get`. I have created a pull request to fix this issue in the mockery project.
see: https://github.com/vektra/mockery/issues/397

This pull request removes the homegrown mocks in `light/provider/mock` in favor of mockery mocks.

Adds a simple benchmark only mock to avoid the overhead of `reflection` that `mockery` incurs.

part of #5274

There are many `//go:generate mockery` lines in the source code.
This change adds a make target to invoke these mock generations.
This change also invokes the mock invocations and adds the resulting mocks to the repo.

## Description

remove IAVL as a Tendermint dependency.

closes #5694 

I dont think this needs a changelog entry.

## Description

revert #5523 to avoid breaking changes

## 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.

* add time warping lunatic attack test

* create too high and connecton refused errors and add to the light client provider

* add height check to provider

* introduce block lag

* add detection logic for processing forward lunatic attack

* add node-side verification logic

* clean up tests and formatting

* update adr's

* update testing

* fix fetching the latest block

* format

* update changelog

* implement suggestions

* modify ADR's

* format

* clean up node evidence verification

Introduces heuristics that track the amount of no responses or unavailable blocks a provider has for more robust provider handling by the light client. Use concurrent calls to all witnesses when a new primary is needed.

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
