Creates a new byte buffer whose content is a shared subsequence of
this buffer's content.
<p> The content of the new buffer will start at this buffer's current
position. 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 position will be zero, its capacity and its limit
will be the number of bytes remaining in this buffer, and its mark
will be undefined. 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>
