Creates a new byte buffer that shares this buffer's content.
<p> The content of the new buffer will be that of this buffer. Changes
to this buffer's content will be visible in the new buffer, and vice
versa; the two buffers' position, limit, and mark values will be
independent.
<p> The new buffer's capacity, limit, position, and mark values will be
identical to those of this buffer. The new buffer will be direct if,
and only if, this buffer is direct, and it will be read-only if, and
only if, this buffer is read-only. </p>
