Minor change to approximateNumEntries() method in CompositeReadOnlyKeyValueStore class.
long total = 0;
for (ReadOnlyKeyValueStore<K, V> store : stores) {
total += store.approximateNumEntries();
}
return total < 0 ? Long.MAX_VALUE : total;
The check for negative value seems to account for wrapping. However, wrapping can happen within the for loop. So the check should be performed inside the loop.

When logging is disabled and there are state stores the task never transitions from restoring to running. This is because we only ever check if the task has state stores and return false on initialization if it does. The check should be if we have changelog partitions, i.e., we need to restore.

Closes#3948 from mjsax/kafka-4593-illegal-state-exception-in-restore
The `metric.reporters` description in the documentation says to implement the `MetricReporter` class, but the actual class is `MetricsReporter`. [MetricsReporter.java](https://github.com/apache/kafka/blob/trunk/clients/src/main/java/org/apache/kafka/common/metrics/MetricsReporter.java)
The configurations documentation is also inconsistent as some references to classes do not have the full package name while others do.

This is the polished version.
1. The old merge() method in StreamsBuilder has been removed,
2. The merge() method in KStreamBuilder was changed so that it would use the single variable argument
rather than several variable arguments in the KStreamImpl implementation
3. The merge() method in KStream has been declared as final and tests have been added to test correctness.

The parameter is already called `mapper` in the KStreamImpl class. I think it was probably named `processor` here because it was copy/pasted from some other signature. This sees trivial enough to not require a jira as per the contribution guidelines.
