* WIP: Get rid of request multiplexer.
* WIP
* Receiver for handling of incoming requests.
* Get rid of useless `Fault` abstraction.
The things the type system let us do are not worth getting abstracted in
its own type. Instead error handling is going to be merely a pattern.
* Make most things compile again.
* Port availability distribution away from request multiplexer.
* Formatting.
* Port dispute distribution over.
* Fixup statement distribution.
* Handle request directly in collator protocol.
+ Only allow fatal errors at top level.
* Use direct request channel for availability recovery.
* Finally get rid of request multiplexer
Fixes#2842 and paves the way for more back pressure possibilities.
* Fix overseer and statement distribution tests.
* Fix collator protocol and network bridge tests.
* Fix tests in availability recovery.
* Fix availability distribution tests.
* Fix dispute distribution tests.
* Add missing dependency
* Typos.
* Review remarks.
* More remarks.
* Wip
* Increase proposer timeout.
* WIP.
* Better timeout values now that we are going to be connected to all nodes. (#2778)
* Better timeout values.
* Fix typo.
* Fix validator bandwidth.
* Fix compilation.
* Better and more consistent sizes.
Most importantly code size is now 5 Meg, which is the limit we currently
want to support in statement distribution.
* Introduce statement fetching request.
* WIP
* Statement cache retrieval logic.
* Review remarks by @rphmeier
* Fixes.
* Better requester logic.
* WIP: Handle requester messages.
* Missing dep.
* Fix request launching logic.
* Finish fetching logic.
* Sending logic.
* Redo code size calculations.
Now that max code size is compressed size.
* Update Cargo.lock (new dep)
* Get request receiver to statement distribution.
* Expose new functionality for responding to requests.
* Cleanup.
* Responder logic.
* Fixes + Cleanup.
* Cargo.lock
* Whitespace.
* Add lost copyright.
* Launch responder task.
* Typo.
* info -> warn
* Typo.
* Fix.
* Fix.
* Update comment.
* Doc fix.
* Better large statement heuristics.
* Fix tests.
* Fix network bridge tests.
* Add test for size estimate.
* Very simple tests that checks we get LargeStatement.
* Basic check, that fetching of large candidates is performed.
* More tests.
* Basic metrics for responder.
* More metrics.
* Use Encode::encoded_size().
* Some useful spans.
* Get rid of redundant metrics.
* Don't add peer on duplicate.
* Properly check hash
instead of relying on signatures alone.
* Preserve ordering + better flood protection.
* Get rid of redundant clone.
* Don't shutdown responder on failed query.
And add test for this.
* Smaller fixes.
* Quotes.
* Better queue size calculation.
* A bit saner response sizes.
* Fixes.
