KAFKA-3933: close deepIterator during log recovery
Avoids leaking native memory and hence crashing brokers on bootup due to
running out of memory.
Introduces `kafka.common.ClosableIterator`, which is an iterator that
can be closed, and changes the signature of
`ByteBufferMessageSet.deepIterator` to return it, then changes the
callers to always close the iterator.
This is a followup from https://github.com/apache/kafka/pull/1598 with more
native memory leaks in the broker code found and fixed.
