* dtable.cc (dtable::init_std_file_from_handle): Mention that console

Browse Source 
handles are kernel objects since Windows 8.
	* fhandler.h (enum conn_state): Add "listener" state.
	(class fhandler_socket): Drop listener status flag.
	(fhandler_socket::lseek): Return -1 and errno ESPIPE.
	(fhandler_serial::lseek): Ditto.
	* fhandler_socket.cc (fhandler_socket::listen): Set connect_state to
	listener.  Add comment.
	(fhandler_socket::accept4): Explicitely check if the socket is listening
	and fail with EINVAL, if not.  Explain why we have to do that.
	(fhandler_socket::recv_internal): Explicitely check if the socket is
	connected if it's a stream socket.  Explain why we have to do that.
	(fhandler_socket::getpeereid): Drop now redundant test.
