Description

There are some problems with harmony Selector:
1. When a serversocket channel does not bind anything, selector should return acceptable. In this situation, poll return POLLHUP. I add this flag to the native code.
2. The same as 1, when a socketChannel does not connect any anything, selector should return connectable. In this situation, poll return POLLHUP, I also add this flag to the native code.
3. As the spec said, selector should also return if an error occurred. I'm not testing the error condition, but I add POLLERR to the native code.
4. If user change the interested operations of a selector, this selector should treated as a new one (but with the same SelectionKey). On the other hand, if the selector was return once and no interested operation changed, it should not be selected next time. I have add a flag stateChange in the SelectionKeyImpl to save this state.
