* Makefile: always pull image in proto-gen-docker. (#5953)
The `proto-gen-docker` target didn't pull an updated Docker image, and would use a local image if present which could be outdated and produce wrong results.
* test: fix TestPEXReactorRunning data race (#5955)
Fixes#5941.
Not entirely sure that this will fix the problem (couldn't reproduce), but in any case this is an artifact of a hack in the P2P transport refactor to make it work with the legacy P2P stack, and will be removed when the refactor is done anyway.

* p2p: make PeerManager.DialNext() and EvictNext() block (#5947)
See #5936 and #5938 for background.
The plan was initially to have `DialNext()` and `EvictNext()` return a channel. However, implementing this became unnecessarily complicated and error-prone. As an example, the channel would be both consumed and populated (via method calls) by the same driving method (e.g. `Router.dialPeers()`) which could easily cause deadlocks where a method call blocked while sending on the channel that the caller itself was responsible for consuming (but couldn't since it was busy making the method call). It would also require a set of goroutines in the peer manager that would interact with the goroutines in the router in non-obvious ways, and fully populating the channel on startup could cause deadlocks with other startup tasks. Several issues like these made the solution hard to reason about.
I therefore simply made `DialNext()` and `EvictNext()` block until the next peer was available, using internal triggers to wake these methods up in a non-blocking fashion when any relevant state changes occurred. This proved much simpler to reason about, since there are no goroutines in the peer manager (except for trivial retry timers), nor any blocking channel sends, and it instead relies entirely on the existing goroutine structure of the router for concurrency. This also happens to be the same pattern used by the `Transport.Accept()` API, following Go stdlib conventions, so all router goroutines end up using a consistent pattern as well.

* p2p: improve peerStore prototype (#5954)
This improves the `peerStore` prototype by e.g.:
* Using a database with Protobuf for persistence, but also keeping full peer set in memory for performance.
* Simplifying the API, by taking/returning struct copies for safety, and removing errors for in-memory operations.
* Caching the ranked peer set, as a temporary solution until a better data structure is implemented.
* Adding `PeerManagerOptions.MaxPeers` and pruning the peer store (based on rank) when it's full.
* Rewriting `PeerAddress` to be independent of `url.URL`, normalizing it and tightening semantics.
* p2p: simplify PeerManager upgrade logic (#5962)
Follow-up from #5947, branched off of #5954.
This simplifies the upgrade logic by adding explicit eviction requests, which can also be useful for other use-cases (e.g. if we need to ban a peer that's misbehaving). Changes:
* Add `evict` map which queues up peers to explicitly evict.
* `upgrading` now only tracks peers that we're upgrading via dialing (`DialNext` → `Dialed`/`DialFailed`).
* `Dialed` will unmark `upgrading`, and queue `evict` if still beyond capacity.
* `Accepted` will pick a random lower-scored peer to upgrade to, if appropriate, and doesn't care about `upgrading` (the dial will fail later, since it's already connected).
* `EvictNext` will return a peer scheduled in `evict` if any, otherwise if beyond capacity just evict the lowest-scored peer.
This limits all of the `upgrading` logic to `DialNext`, `Dialed`, and `DialFailed`, making it much simplier, and it should generally do the right thing in all cases I can think of.
* p2p: add PeerManager.Advertise() (#5957)
Adds a naïve `PeerManager.Advertise()` method that the new PEX reactor can use to fetch addresses to advertise, as well as some other `FIXME`s on address advertisement.
* blockchain v0: fix waitgroup data race (#5970)
## Description
Fixes the data race in usage of `WaitGroup`. Specifically, the case where we invoke `Wait` _before_ the first delta `Add` call when the current waitgroup counter is zero. See https://golang.org/pkg/sync/#WaitGroup.Add.
Still not sure how this manifests itself in a test since the reactor has to be stopped virtually immediately after being started (I think?).
Regardless, this is the appropriate fix.

* p2p: add prototype PEX reactor for new stack (#5971)
This adds a prototype PEX reactor for the new P2P stack.
* proto/p2p: rename PEX messages and fields (#5974)
Fixes#5899 by renaming a bunch of P2P Protobuf entities (while maintaining wire compatibility):
* `Message` to `PexMessage` (as it's only used for PEX messages).
* `PexAddrs` to `PexResponse`.
* `PexResponse.Addrs` to `PexResponse.Addresses`.
* `NetAddress` to `PexAddress` (as it's only used by PEX).
* p2p: resolve PEX addresses in PEX reactor (#5980)
This changes the new prototype PEX reactor to resolve peer address URLs into IP/port PEX addresses itself. Branched off of #5974.
I've spent some time thinking about address handling in the P2P stack. We currently use `PeerAddress` URLs everywhere, except for two places: when dialing a peer, and when exchanging addresses via PEX. We had two options:
1. Resolve addresses to endpoints inside `PeerManager`. This would introduce a lot of added complexity: we would have to track connection statistics per endpoint, have goroutines that asynchronously resolve and refresh these endpoints, deal with resolve scheduling before dialing (which is trickier than it sounds since it involves multiple goroutines in the peer manager and router and messes with peer rating order), handle IP address visibility issues, and so on.
2. Resolve addresses to endpoints (IP/port) only where they're used: when dialing, and in PEX. Everywhere else we use URLs.
I went with 2, because this significantly simplifies the handling of hostname resolution, and because I really think the PEX reactor should migrate to exchanging URLs instead of IP/port numbers anyway -- this allows operators to use DNS names for validators (and can easily migrate them to new IPs and/or load balance requests), and also allows different protocols (e.g. QUIC and `MemoryTransport`). Happy to discuss this.

@p4u from vocdoni.io reported that the mempool might behave incorrectly under a
high load. The consequences can range from pauses between blocks to the peers
disconnecting from this node.
My current theory is that the flowrate lib we're using to control flow
(multiplex over a single TCP connection) was not designed w/ large blobs
(1MB batch of txs) in mind.
I've tried decreasing the Mempool reactor priority, but that did not
have any visible effect. What actually worked is adding a time.Sleep
into mempool.Reactor#broadcastTxRoutine after an each successful send ==
manual control flow of sort.
As a temporary remedy (until the mempool package
is refactored), the max-batch-bytes was disabled. Transactions will be sent
one by one without batching
Closes#5796
When set to true, an invalid transaction will be kept in the cache (this may help some applications to protect against spam).
NOTE: this is a temporary config option. The more correct solution would be to add a TTL to each transaction (i.e. CheckTx may return a TTL in ResponseCheckTx).
Closes: #5751
After a reactor has failed to parse an incoming message, it shouldn't output the "bad" data into the logs, as that data is unfiltered and could have anything in it. (We also don't think this information is helpful to have in the logs anyways.)
`abci.Client`:
- Sync and Async methods now accept a context for cancellation
* grpc client uses context to cancel both Sync and Async requests
* local client ignores context parameter
* socket client uses context to cancel Sync requests and to drop Async requests before sending them if context was cancelled prior to that
- Async methods return an error
* socket client returns an error immediately if queue is full for Async requests
* local client always returns nil error
* grpc client returns an error if context was cancelled before we got response or the receiving queue had a space for response (do not confuse with the sending queue from the socket client)
- specify clients semantics in [doc.go](https://raw.githubusercontent.com/tendermint/tendermint/27112fffa62276bc016d56741f686f0f77931748/abci/client/doc.go)
`mempool.TxInfo`
- add optional `Context` to `TxInfo`, which can be used to cancel `CheckTx` request
Closes#5190
found out this issue when trying to decouple mempool reactor with its
underlying clist implementation.
according to its comment, the test `TestReactorNoBroadcastToSender` is
intended to make sure that a peer shouldn't send tx back to its origin.
however, the current test forgot to init peer state key, thus the code
will get stuck at waiting for peer to catch up state *instead of* skipping
sending tx back:
b8d08b9ef4/mempool/reactor.go (L216-L226)
this PR fixes the issue by init peer state key.

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):
```

: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
