Description

Integrate ouroboros-network in preparation for cardano-node-10.2.0 release

See IntersectMBO/cardano-node#6040 for overall progress

[jasagredo]

FYI, the cardano-ledger commit in the SRP is gone. I suspect the new one is IntersectMBO/cardano-ledger@3fe0221 or IntersectMBO/cardano-ledger@12f6aa6 (the merge commit of the PR).

@lehins This branch should incorporate the latest commits in blockfetch/milestone-1. In particular it is missing:

9e001f766 * origin/blockfetch/milestone-1 Make `ChainSelStarvation` carry an `Enclosed`
a36fd875d * Enrich comment about disabled `mustReplyTimeout`
513f34756 * Fix tests that relied on default timeouts
4e561806d * Rework default ChainSyncTimeouts in peer simulator
bee2c8445 * Log ChainSync mini-protocol events if need be
7b04c2822 * Make the `DynamoStarting` trace more explicit
ef092ca75 * Add a `TraceDrainingThePipe` event
3f8da3b60 * Improve and clarify CSJ documentation

I created #1351 which you can merge right away.

I removed the no changelog label. Please only apply it at the very end when merging this iff there are changes in non-testing libraries (those whose name is not prefixed by unstable-) that do not require a changelog entry. For tests/benchmarks/unstable-*/executables, the CI check should already ignore changes in those.

If we apply this label too early in the process, we risk introducing changes in the meantime which don't end up in the Changelog.

This is now based on #1179, and will be rebased when that is merged
