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`.
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
This is useful for custom state sync `StateProvider` implementations that need to build new states for bootstrapping the node. It will also be useful when implementing other mechanisms to bootstrap nodes, e.g. #4642 and #3713.
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.
Closes: #4530
This PR contains logic for both submitting an evidence by the light client (lite2 package) and receiving it on the Tendermint side (/broadcast_evidence RPC and/or EvidenceReactor#Receive). Upon receiving the ConflictingHeadersEvidence (introduced by this PR), the Tendermint validates it, then breaks it down into smaller pieces (DuplicateVoteEvidence, LunaticValidatorEvidence, PhantomValidatorEvidence, PotentialAmnesiaEvidence). Afterwards, each piece of evidence is verified against the state of the full node and added to the pool, from which it's reaped upon block creation.
* rpc/client: do not pass height param if height ptr is nil
* rpc/core: validate incoming evidence!
* only accept ConflictingHeadersEvidence if one
of the headers is committed from this full node's perspective
This simplifies the code. Plus, if there are multiple forks, we'll
likely to receive multiple ConflictingHeadersEvidence anyway.
* swap CommitSig with Vote in LunaticValidatorEvidence
Vote is needed to validate signature

http is a provider and should not be used as a client

- do not send any LastCommitInfo.Votes for 1st block.
- use cs.LastValidators (not cs.Validators) in recordMetrics when counting missing validators
note:
remember that the first LastCommit is intentionally empty, so it makes
sense for LastCommitInfo.Votes to also be empty. Because we can't really
tell if validator signed or not. Similar for ^ metrics, we can't say if
particular validator was missing or not.

BREAKING
Example response:
```json
{
"jsonrpc": "2.0",
"id": "",
"result": {
"height": "2109",
"txs_results": null,
"begin_block_events": null,
"end_block_events": null,
"validator_updates": null,
"consensus_param_updates": null
}
}
```
Old result consisted of ABCIResponses struct and height. Exposing
internal ABCI structures (which we store in state package) in RPC seems
bad to me for the following reasons:
1) high risk of breaking the API when somebody changes internal structs
(HAPPENED HERE!)
2) RPC is aware of ABCI, which I'm not sure we want
when the user searches for a tx (hash=X)
This PR fixes error handling for performing a txindex search.
TxIndex.Get returns
(txresult, nil) if the transaction is found.
(nil, nil) if the transaction is not found.
(nil, error) if error is occurred.
Therefore, if res is not nil, I think TxIndex.Search should return (txresult, nil).
Previously, however, this was not a problem because errors.Wrap returns nil if its first argument err is nil.
## Issue
Why this pr:
When restarting chain node, sometimes we lost tx index about recent(around 80)blocks, and some client complains that they can't find the tx by RPC call(tx_search) when the tx do exist in the block.
I try to partially fix this issue in a simple way by writing the index data in a sync way.
There is no performance difference under 1K TPS according to our test.
It is still possible that lost index data after restarting the node, but only 2 block data will lost at most.
I try to totally fix this in https://github.com/tendermint/tendermint/pull/3847/files, but this one is simple and can solve most part of the issue. Please review first, thks.

Performance drop is pretty steep, but I think it's the right thing to do UNTIL we have a WAL.
