bcf10d5bae p2p: peer state init too late and pex message too soon (#3634)
* fix peer state init to late

Peer does not have a state yet. We set it in AddPeer.
We need an new interface before mconnection is started

* pex message to soon

fix reconnection pex send too fast,
error is caused lastReceivedRequests is still
not deleted when a peer reconnected

* add test case for initpeer

* add prove case

* remove potentially infinite loop

* Update consensus/reactor.go

Co-Authored-By: guagualvcha <baifudong@lancai.cn>

* Update consensus/reactor_test.go

Co-Authored-By: guagualvcha <baifudong@lancai.cn>

* document Reactor interface better

* refactor TestReactorReceiveDoesNotPanicIfAddPeerHasntBeenCalledYet

* fix merge conflicts

* blockchain: remove peer's ID from the pool in InitPeer

Refs #3338

* pex: resetPeersRequestsInfo both upon InitPeer and RemovePeer

* ensure RemovePeer is always called before InitPeer

by removing the peer from the switch last (after we've stopped it and
removed from all reactors)

* add some comments for ConsensusReactor#InitPeer

* fix pex reactor

* format code

* fix spelling

* update changelog

* remove unused methods

* do not clear lastReceivedRequests upon error

only in RemovePeer

* call InitPeer before we start the peer!

* add a comment to InitPeer

* write a test

* use waitUntilSwitchHasAtLeastNPeers func

* bring back timeouts

* Test to ensure Receive panics if InitPeer has not been called

* panic if peer has no state

https://github.com/tendermint/tendermint/issues/2721#issuecomment-435347165

It's confusing that sometimes we check if peer has a state, but most of
the times we expect it to be there

1. add79700b5/mempool/reactor.go (L138)
2. add79700b5/rpc/core/consensus.go (L196) (edited)

I will change everything to always assume peer has a state and panic
otherwise

that should help identify issues earlier

* abci/localclient: extend lock on app callback

App callback should be protected by lock as well (note this was already
done for InitChainAsync, why not for others???). Otherwise, when we
execute the block, tx might come in and call the callback in the same
time we're updating it in execBlockOnProxyApp => DATA RACE

Fixes #2721

Consensus state is locked

* consensus: use read lock in Receive#VoteMessage

* use defer to unlock mutex because application might panic

* use defer in every method of the localClient

* add a changelog entry

* drain channels before Unsubscribe(All)

Read 55362ed766/libs/pubsub/pubsub.go (L13)
for the detailed explanation of the issue.

We'll need to fix it someday. Make sure to keep an eye on
https://github.com/tendermint/tendermint/blob/master/docs/architecture/adr-033-pubsub.md

* retry instead of panic when peer has no state in reactors other than consensus

in /dump_consensus_state RPC endpoint, skip a peer with no state

* rpc/core/mempool: simplify error messages

* rpc/core/mempool: use time.After instead of timer

also, do not log DeliverTx result (to be consistent with other memthods)

* unlock before calling the callback in reqRes#SetCallback
