(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().
* java/net/DatagramSocket.java (receive): Don't throw an
IllegalBlockingModeException if we have a non-blocking
channel which initiated this operation.
(send): Likewise.
