* fhandler.h (fhandler_socket::is_unconnected): Constify.

Browse Source 
(fhandler_socket::is_connect_pending): Ditto.
	(fhandler_socket::is_connected): Ditto.
	(fhandler_socket::set_connect_state): New method.
	(struct select_record): Add member `except_on_write'.
	(select_record::select_record): Initialize all bool values to `false'.
	* fhandler_socket.cc: Use set_connect_state() method throughout.
	(fhandler_socket::connect): Set state always to connected if connection
	isn't pending.
	* net.cc (cygwin_getsockopt): Revert erroneous previous patch.
	* select.cc (set_bits): Check for `except_on_write'.  Set fd in
	write_fds if set.  Set connect state to connected if fd has been
	returned by WINSOCK_SELECT.
	(peek_socket): Check for `except_on_write'.
	(start_thread_socket): Ditto.
	(fhandler_socket::select_write): Don't set `write_ready' if connect
	is pending.  Set `except_on_write' if connect is pending.
