The event loop uses a `select` on multiple channels. However, reading from a closed channel in Go always yields the channel's zero value. The processor and scheduler close their channels when done, and since these channels are always ready to receive, the event loop keeps spinning on them.
This changes `routine.terminate()` to not close the channel, and also removes `stopDemux` and instead uses `events` channel closure to signal event loop termination.
Fixes#4687.
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 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.
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
Fixes#2593@alexanderbez This is used in a single place in the SDK, how upset are you about removing it?

The checklist and message in the default PR description were sometimes getting

to a comment from a [Probot tool](https://probot.github.io/apps/auto-comment/).
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
Reduce the number of targets and make the buildsystem more
flexible by parsing the TENDERMINT_BUILD_OPTIONS command
line variable (a-la Debian, inspired by dpkg-buildpackage's
DEB_BUILD_OPTIONS), e.g:
$ make install TENDERMINT_BUILD_OPTIONS='cleveldb'
replaces the old:
$ make install_c
Options can be mix&match'd, e.g.:
$ make install TENDERMINT_BUILD_OPTIONS='cleveldb race nostrip'
Three options are available:
- nostrip: don't strip debugging symbols nor DWARF tables.
- cleveldb: use cleveldb as db backend instead of goleveldb;
it switches on the CGO_ENABLED Go environment variale.
- race: pass -race to go build and enable data race detection.
This changeset is a port of gaia pull request: cosmos/gaia#363.
Fixes#4739, kind of. See #4740 for the proper fix.

- Move core stateless validation of the Header type to a ValidateBasic method.
- Call header.ValidateBasic during a SignedHeader validation.
- Call header.ValidateBasic during a PhantomValidatorEvidence validation.
- Call header.ValidateBasic during a LunaticValidatorEvidence validation.

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
Updates our Security Policy with takeaways from Security Advisory
Lavender and the associated security releases.
Thank you to @melekes and @alessio for reviewing earlier versions
of this document.

Followup from #4588. Allow the first `SaveBlock()` call in an empty block store to be at any height, to start from a truncated block history. Subsequent `SaveBlock()` calls must be for contiguous blocks.

The service logging can be a bit unclear. For example, with state sync it would log:
```
I[2020-04-20|08:40:47.366] Starting StateSync module=statesync impl=Reactor
I[2020-04-20|08:40:47.834] Starting state sync module=statesync
```
Where the first message is the reactor service startup, and the second message is the start of the actual state sync process. This clarifies the first message by changing it to `Starting StateSync service`.
