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`.

prometheous change:
due to UninstrumentedHandler, being deprecated in the future
empty branch = empty if or else statement
didn't delete them entirely but commented
couldn't find a reason to have them
could not replicate the issue #3406
but if want to keep it commented then we should comment out the if statement as well
* go routines in blockchain reactor
* Added reference to the go routine diagram
* Initial commit
* cleanup
* Undo testing_logger change, committed by mistake
* Fix the test loggers
* pulled some fsm code into pool.go
* added pool tests
* changes to the design
added block requests under peer
moved the request trigger in the reactor poolRoutine, triggered now by a ticker
in general moved everything required for making block requests smarter in the poolRoutine
added a simple map of heights to keep track of what will need to be requested next
added a few more tests
* send errors to FSM in a different channel than blocks
send errors (RemovePeer) from switch on a different channel than the
one receiving blocks
renamed channels

* address golangci comments :)
* Added timeout on next block needed to advance
* updating docs and cleanup
* fix issue in test from previous cleanup
* cleanup
* Added termination scenarios, tests and more cleanup
* small fixes to adr, comments and cleanup
* Fix bug in sendRequest()
If we tried to send a request to a peer not present in the switch, a
missing continue statement caused the request to be blackholed in a peer
that was removed and never retried.
While this bug was manifesting, the reactor kept asking for other
blocks that would be stored and never consumed. Added the number of
unconsumed blocks in the math for requesting blocks ahead of current
processing height so eventually there will be no more blocks requested
until the already received ones are consumed.
* remove bpPeer's didTimeout field
* Use distinct err codes for peer timeout and FSM timeouts
* Don't allow peers to update with lower height

Fixes#3457
The topic of the issue is that : write a BlockRequest int requestsCh channel will create an timer at the same time that stop the peer 15s later if no block have been received . But pop a BlockRequest from requestsCh and send it out may delay more than 15s later. So that the peer will be stopped for error("send nothing to us").
Extracting requestsCh into its own goroutine can make sure that every BlockRequest been handled timely.
Instead of the requestsCh handling, we should probably pull the didProcessCh handling in a separate go routine since this is the one "starving" the other channel handlers. I believe the way it is right now, we still have issues with high delays in errorsCh handling that might cause sending requests to invalid/ disconnected peers.
