Add test vectors for all reactors
- [x] state-sync

- [x] mempool
- [x] p2p
- [x] evidence
- [ ] light?
this PR is primarily oriented at testvectors for things going over the wire. should we expand the testvectors into types as well?
Closes: #XXX
## Description
This PR wraps the stdlib sync.(RW)Mutex & godeadlock.(RW)Mutex. This enables using go-deadlock via a build flag instead of using sed to replace sync with godeadlock in all files
Closes: #3242
In order to have more control over the mempool implementation,
introduce a new exported function RemoveTxByKey.
Export also TxKey() and TxKeySize. Use TxKeySize const instead of
sha256.size, so future changes on the hash function won't break the API.
Allows using a TxKey (32 bytes reference) as parameter instead of
the complete array set. So the application layer does not need to
keep track of the whole transaction but only of the sha256 hash (32 bytes).
This function is useful when mempool.Recheck is disabled.
Allows the Application layer to implement its own cleaning mechanism
without having to re-implement the whole mempool interface.
Mempool.Update() would probably also need to change from txBytes to txKey,
but that would require to change the Interface thus will break backwards
compatibility. For now RemoveTxByKey() looks like a good compromise,
it won't break anything and will help to solve some mempool issues from the
application layer.

Commands used (VIM):
```
:args `rg -l errors.Wrap`
:argdo normal @q | update
```
where q is a macros rewriting the `errors.Wrap` to `fmt.Errorf`.
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
Previously, many reactors were initialized with the name "Reactor," which made it difficult to log which reactor was doing what. This changes those reactors' names to something more descriptive.

As per #2127, this refactors the RequestCheckTx ProtoBuf struct to allow for a flag indicating whether a query is a recheck or not (and allows for possible future, more nuanced states).
In order to pass this extended information through to the ABCI app, the proxy.AppConnMempool (and, for consistency, the proxy.AppConnConsensus) interface seems to need to be refactored along with abcicli.Client.
And, as per this comment, I've made the following modification to the protobuf definition for the RequestCheckTx structure:
enum CheckTxType {
New = 0;
Recheck = 1;
}
message RequestCheckTx {
bytes tx = 1;
CheckTxType type = 2;
}
* Refactor ABCI CheckTx to notify of recheck
As per #2127, this refactors the `RequestCheckTx` ProtoBuf struct to allow for:
1. a flag indicating whether a query is a recheck or not (and allows for
possible future, more nuanced states)
2. an `additional_data` bytes array to provide information for those more
nuanced states.
In order to pass this extended information through to the ABCI app, the
`proxy.AppConnMempool` (and, for consistency, the
`proxy.AppConnConsensus`) interface seems to need to be refactored.

* mempool: remove only valid (Code==0) txs on Update
so evil proposers can't drop valid txs in Commit stage.
Also remove invalid (Code!=0) txs from the cache so they can be
resubmitted.
Fixes#3322@rickyyangz:
In the end of commit stage, we will update mempool to remove all the txs
in current block.
// Update mempool.
err = blockExec.mempool.Update(
block.Height,
block.Txs,
TxPreCheck(state),
TxPostCheck(state),
)
Assum an account has 3 transactions in the mempool, the sequences are
100, 101 and 102 separately, So an evil proposal can only package the
101 and 102 transactions into its proposal block, and leave 100 still in
mempool, then the two txs will be removed from all validators' mempool
when commit. So the account lost the two valid txs.
@ebuchman:
In the longer term we may want to do something like #2639 so we can
validate txs before we commit the block. But even in this case we'd only
want to run the equivalent of CheckTx, which means the DeliverTx could
still fail even if the CheckTx passes depending on how the app handles
the ABCI Code semantics. So more work will be required around the ABCI
code. See also #2185

I ran an irishub validator. After the validator node ran several days, I dump the whole goroutine stack. I found that there were hundreds of broadcastTxRoutine. However, the connected peer quantity was less than 30. So I belive that there must be broadcastTxRoutine leakage issue.
According to my analysis, I think the root cause of this issue locate in below code:
select {
case <-next.NextWaitChan():
// see the start of the for loop for nil check
next = next.Next()
case <-peer.Quit():
return
case <-memR.Quit():
return
}
As we know, if multiple paths are avaliable in the same time, then a random path will be selected. Suppose that next.NextWaitChan() and peer.Quit() are both avaliable, and next.NextWaitChan() is chosen.
// send memTx
msg := &TxMessage{Tx: memTx.tx}
success := peer.Send(MempoolChannel, cdc.MustMarshalBinaryBare(msg))
if !success {
time.Sleep(peerCatchupSleepIntervalMS * time.Millisecond)
continue
}
Then next will be non-empty and the peer send operation won't be success. As a result, this go routine will be track into infinite loop and won't be released.
My proposal is to check peer.Quit() and memR.Quit() in every loop no matter whether next is nil.
Closes#1798
This is done by making every mempool tx maintain a list of peers who its received the tx from. Instead of using the 20byte peer ID, it instead uses a local map from peerID to uint16 counter, so every peer adds 2 bytes. (Word aligned to probably make it 8 bytes)
This also required resetting the callback function on every CheckTx. This likely has performance ramifications for instruction caching. The actual setting operation isn't costly with the removal of defers in this PR.
