Loosens the validation so that Kafka can accept duplicate listeners on the same port but if and only if the listeners are valid IP addresses with one address being an IPv4 address and the other being an IPv6 address.

The CRC field of Record Batch was incorrectly documented as int32 while in reality it's an unsigned uint32 field.

KIP-914 introduced a new boolean isLatest into Change to indicate whether a change update represents the latest for the key. Even though Change is serialized into the table repartition topic, the new boolean does not need to be serialized in, because the table repartition map processor performs an optimization to drop records for which isLatest = false. If not for this optimization, the downstream table aggregate would have to drop such records instead, and isLatest would need to be serialized into the repartition topic.
In light of the possibility that isLatest may need to be serialized into the repartition topic in the future, e.g., if other downstream processors are added which need to distinguish between records for which isLatest = true vs isLatest = false, this PR reserves repartition topic formats which include isLatest. Reserving these formats now comes at no additional cost to users since a rolling bounce is already required for the upcoming release due to KIP-904. If we don't reserve them now and instead have to add them later, then another bounce would be required at that time. Reserving formats is cheap, so we choose to do it now.

Currently, the current-state KRaft related metric reports follower state for a broker while technically it should be reported as an observer as the kafka-metadata-quorum tool does.

Documentation only—Minor clarification on how max.warmup.replicas works; specifically, that one "warmup replica" corresponds to a Task that is restoring its state. Also clarifies how max.warmup.replicas interacts with probing.rebalance.interval.ms.

This is the PR for the implementation of KIP-847: https://cwiki.apache.org/confluence/display/KAFKA/KIP-847%3A+Add+ProducerIdCount+metrics
Add ProducerIdCount metric at the broker level:
kafka.server:type=ReplicaManager,name=ProducerIdCount
Added unit tests below to ensure the metric reported the count correctly.

The table of (stateless) transformations uses the transformation name in the first column and a description in the second column. I adjusted the transformation name for FlatMapValues accordingly.

This patch adds a section in security.html about listener configuration. This includes the basics of how to define the security mapping of each listener as well as the configurations to control inter-cluster traffic.
