* gnu/java/net/PlainSocketImpl.java

	(inChannelOperation): New field.
	(isInChannelOperation): New accessor.
	(setInChannelOperation): New modifier.
	* gnu/java/nio/ServerSocketChannelImpl.java
	(accept): Set and reset our server socket's PlainSocketImpl's
	"in channel operation" indicator before and after delegating
	the accept to our server socket.
	* gnu/java/nio/SocketChannelImpl.java
	(connect): Set and reset our socket's PlainSocketImpl's "in channel
	operation" indicator before and after delegating the operation to
	our socket.
	(read): Likewise.
	(write): Likewise.
	* java/net/ServerSocket.java (implAccept): Don't throw an
	IllegalBlockingModeException if we have a non-blocking
	channel which initiated this accept operation.
	* java/net/Socket.java (connect): Don't throw an
	IllegalBlockingModeException if we have a non-blocking
	channel which initiated this connect operation.
	* java/nio/channels/spi/AbstractSelectableChannel.java
	(configureBlocking): Only call implConfigureBlocking() if
	the desired blocking mode is different from our current one.
