Resynced with GNU Classpath

2004-02-06  Mohan Embar  <gnustuff at thisiscool.com>

        * gnu/java/nio/DatagramChannelImpl.java
        (inChannelOperation): New field.
        (isInChannelOperation): New accessor.
        (setInChannelOperation): New modifier.
        (receive): Use capacity() - position() of destination
        buffer instead of remaining(). Set and reset our in channel operation indicator
 before and after delegating
        the receive to our datagram socket. Removed testing code.
        Update destination buffer's current position if it is
        backed by a byte array (hasArray() is true).
        (send): Set and reset our in channel operation indicator
        before and after delegating the send to our datagram socket.
        Removed testing code. Update source buffer's current position
        if it is backed by a byte array (hasArray() is true).
        * gnu/java/nio/SocketChannelImpl.java (read(ByteBuffer)):
        Use capacity() - position() of destination buffer instead
        of remaining().
