Fixes #5422. That turned out to be a whole lot easier than expected.

Backport of #5536.

Before: scheduler receives psBlockProcessed event, but does not mark block as processed because peer timed out (or was removed for other reasons) and all associated blocks were rescheduled.

After: scheduler receives psBlockProcessed event and marks block as processed in any case (even if peer who provided this block errors).

Closes #5387

When a peer is stopped due to some network issue, the Reactor calls scheduler#handleRemovePeer, which removes the peer from the scheduler. BUT the peer stays in the processor, which sometimes could lead to "duplicate block enqueued by processor" panic WHEN the same block is requested by the scheduler again from a different peer. The solution is to return scPeerError, which will be propagated to the processor. The processor will clean up the blocks associated with the peer in purgePeer.

Closes #5513, #5517

Fixes #5439. This is really a workaround for #5519 (unless we require async implementations to return ordered responses, but that kind of defeats the purpose of having an async API).

Secp256k1 was removed in the protobuf migration, this pr adds it back in order to provide this functionality for users (band)

Closes: #5495

Fixes #5511.

* mempool: length prefix txs when getting them from mempool (#5483)

* correctly calculate evidence data size (#5482)

* block: use commit sig size instead of vote size (#5490)

* tx: reduce function to one parameter (#5493)

I forgot to add the date when we cut 0.33.5. This fixes that. It also fixes a header indentation issue for 0.33.8.

Fixes #5371.

Required for #5291 to set timeouts for remote signers.

Required for #5291, to generate configuration files with state sync RPC servers.

previously, the second next could return nil, which would be the reason
for panic on line 275:

memTx := next.Value.(*mempoolTx)

Closes #5408

This change adds some polish to the upgrading instructions for 0.34. The only substantive changes include:
* Calling out ABCI-impacting changes explicitly in the "ABCI Changes" section, even if those changes are also mentioned elsewhere
* Removes `ProofOfTrialPeriod` from consensus params; this change was introduced and then removed.

Reduces the state sync discovery time from 20 to 15 seconds, and makes it configurable.

This caused the node to crash whenever any state sync-related request was called via the ABCI UNIX socket client.

Closes #4489

Fixes #5377 and comments in #4588 (review).

Closes #5145

also applies to light/client

## Description

Add a cmd to docker image and use it to format our proto files. This avoids developers the need to install clang-format

Closes: #XXX

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.

evidence: modify evidence types (#5342)

light: detect light client attacks (#5344)

evidence: refactor evidence pool (#5345)

abci: application evidence prepared by evidence pool (#5354)

Revert the JSON-RPC/WebSocket response serialization format to the
standard way (i.e. a single RPC response per WebSocket text message) to
avoid breaking clients.

Serialization format changes will be discussed in an upcoming ADR.

## Description

Adding a section explaining the state store interface change. I wasn't aware this was used externally. Our infamous API strikes again.

Closes: #XXX

Fixes a couple of test data races. `testing.T` is not concurrency-safe and should not be used in goroutines at all.

Broke in #5356.
