Use LinkedList in org.apache.commons.io.output.AbstractByteArrayOutputStream

Hi,

org.apache.commons.io.output.AbstractByteArrayOutputStream is super class which
(unlike java.io.ByteArrayOutputStream)
not realocate memory/copy arrays - if data buffer is groving.

Instead of it use List of 1KB byte[] chunks and simply add new chunk into list.

private final List<byte[]> buffers = new ArrayList<>();

But as List implementation there is used "ArrayList" so the "array of pointers to chunks" is stil realocated in memory.

I suggest to use LinkedList instead.

With best regards
