* test-vectors for backwards compatibility:

 - copy & paste test-vectors from v0.33.5 to ensure
 backwards compatibility for vote's SignBytes

* WIP: everything besides time seems to match :-/

* almost

* Found the culprit: field nums weren't consecutive ints ...

* fix order of partset header too

* this last votes-related test can easily be fixed

* some minor changes and fix last failing test

* move proto types back to stdtime, fix various linting

* use libs/protoio

* remvoe commented code

* add comments

* fix tests

* uncomment testscases

* dont ignore error panic

* fix signable test

* fix happy path testing

* fix comment

## Description

This pr removes amino from tendermint. 

Closes: #4278

## Description

This PR removes simple prefix from all types in the crypto/merkle directory.

The two proto types `Proof` & `ProofOp` have been moved to the `proto/crypto/merkle` directory.

proto messge `Proof` was renamed to `ProofOps` and `SimpleProof` message to `Proof`. 

Closes: #2755

## Description

migrate consensus to protobuf

Closes: #XXX

Creates Amnesia Evidence which is formed from Potential Amnesia Evidence with either a matching proof or after a period of time denoted as the Amnesia Trial Period. This also adds the code necessary so that Amnesia Evidence can be validated and committed on a block

LastCommitRound should always be >= 0 for heights > 1.

In State.updateToState, last precommit is computed  only when round
greater than -1 and has votes. But "LastCommit" is always updated
regardless of the condition. If there's no last precommit, "LastCommit"
is set to (*types.VoteSet)(nil). That's why "LastCommit" can be -1 for
heights > 1.

To fix it, only update State.RoundState.LastCommit when there is last
precommit.

Fixes #2737

validation of lunatic evidence requires that the node retrieve the header at the height of the infringement from the block store for comparison

## Description

in consensus/state.go, when calulating metrics, retrieve address (ergo, pubkey) once prior to iterating over validatorset to ensure we do not make excessive calls to signer.

Partially closes: #4865

attempt to fix #4270

TestMempoolProgressAfterCreateEmptyBlocksInterval and other tests which
rely on ensureTimeout

Refs #3406

cs.Logger is protected by a global mutex, so it cannot be a reason for
the halt in #3401.

## Description

various linitng fixes

Closes #4603

Commands used (VIM):

```
:args `rg -l errors.Wrap`
:argdo normal @q | update
```

where q is a macros rewriting the `errors.Wrap` to `fmt.Errorf`.

creates a proof of lock change which is an array of votes that proves the validator was permitted to change locked block and vote again. This proof is stored in the evidence pool and is used as a part of amnesia evidence

The number of evidence that can be committed in a single block is capped by a new evidence parameter called MaxNum

allow ReapX and CheckTx functions to run in parallel, making it not possible to block certain proposers from creating a new block.

Closes: #2972

correct test in consensus so that node relocks on same block and then changes lock when majority of another block is reached

* consensus: fix TestSimulateValidatorsChange

* fix selfIndex calculation

* exit from goroutine after 1 sec

* reuse the function

Closes #4766

Predominantly following the discussions regarding the conventions of using mocks, I have decided to revert back to the previous state where mocks were specialized and stored in the separate packages that used them rather then have a generalized mock in the evidence package.

This also was a problem as the state package were running tests too slow and occasionally timing out unnecessarily.

For the replay file I renamed mockEvidencePool to emptyEvidencePool to illustrate that it was intentionally like this and not give the impression that testing software was being used in production

Closes: #4786

## Description
- enable nolintlint
- disable linting on tests

Closes: #XXX

Fixes #828. Adds state sync, as outlined in [ADR-053](https://github.com/tendermint/tendermint/blob/master/docs/architecture/adr-053-state-sync-prototype.md). See related PRs in Cosmos SDK (https://github.com/cosmos/cosmos-sdk/pull/5803) and Gaia (https://github.com/cosmos/gaia/pull/327).

This is split out of the previous PR #4645, and branched off of the ABCI interface in #4704. 

* Adds a new P2P reactor which exchanges snapshots with peers, and bootstraps an empty local node from remote snapshots when requested.

* Adds a new configuration section `[statesync]` that enables state sync and configures the light client. Also enables `statesync:info` logging by default.

* Integrates state sync into node startup. Does not support the v2 blockchain reactor, since it needs some reorganization to defer startup.

to prevent malicious nodes from sending us large messages (~21MB, which
is the default `RecvMessageCapacity`)

This allows us to remove unnecessary `maxMsgSize` check in `decodeMsg`. Since each channel has a msg capacity set to `maxMsgSize`, there's no need to check it again in `decodeMsg`.

Closes #1503

Previously, many reactors were initialized with the name "Reactor," which made it difficult to log which reactor was doing what. This changes those reactors' names to something more descriptive.
