---------------------------------

Hi, Paulex:
           I decided to add receive and send related features also in this issue. After that, I will try some test for performance.  :)

Thanks,
Leo.

> As spec says, "Given a direct byte buffer, the Java virtual machine will make a best effort to perform native I/O operations directly upon it. That is, it will attempt to avoid copying the buffer's content to (or from) an intermediate buffer before (or after) each invocation of one of the underlying operating system's native I/O operation". However, in Harmony nio, DatagramChannelImpl does not differentiate whether the byte buffer is direct or not.
