f23f21f001 evidence: protect valToLastHeight w/ mtx
to prevent data races

note: when we check the ConflictingHeadersEvidence, the copy is used.

Closes #4749

Also, iterate over valToLastHeight instead of loading validators. While it might be slower than accessing a single key in goleveldb, the new code is better adapted to ConsensusParams changes.

50e47357d8 improve evidence db #4722
merged the existing store into pool, consolidated the three buckets into two, used block height as a marked for committed evidence, evidence list recovers on start up, improved error handling

41c11ad2c1 evidence: handling evidence from light client(s) (#4532)
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

* no need to embed client

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

11fa625934 evidence: both MaxAgeDuration and MaxAgeNumBlocks need to be surpassed (#4667)
for evidence to be considered expired. otherwise, a cabal group can
  manipulate block time to make a particular evidence too old.
