MINOR: Add more validation during KRPC deserialization

When deserializing KRPC (which is used for RPCs sent to Kafka, Kafka Metadata records, and some
    other things), check that we have at least N bytes remaining before allocating an array of size N.

    Remove DataInputStreamReadable since it was hard to make this class aware of how many bytes were
    remaining. Instead, when reading an individual record in the Raft layer, simply create a
    ByteBufferAccessor with a ByteBuffer containing just the bytes we're interested in.

    Add SimpleArraysMessageTest and ByteBufferAccessorTest. Also add some additional tests in
    RequestResponseTest.
