* fhandler.h (UNCONNECTED): New define.

	(CONNECT_PENDING): Ditto.
	(CONNECTED): Ditto.
	(class fhandler_socket): Add member `had_connect_or_listen'.
	Add member functions `is_unconnected', `is_connect_pending' and
	`is_connected'.
	* fhandler_socket.cc (fhandler_socket::connect): Set member
	`had_connect_or_listen' according to return code of WinSock
	call.
	(fhandler_socket::listen): Ditto.
	* net.cc (cygwin_getsockopt): Modify SO_ERROR return value in
	case of socket with pending connect().
	* select.cc (peek_socket): Only add socket to matching fd_set
	if it's not "ready".  Call WINSOCK_SELECT only if at least one
	socket is in one of the fd_sets.
	(start_thread_socket): Only add socket to matching fd_set
	if it's not "ready".
	(fhandler_socket::select_write): Set write_ready to true also
