* fhandler_socket.cc (fhandler_socket::connect): Don't restrict
WSAEINVAL -> WSAEISCONN conversion to nonblocking sockets.
(fhandler_socket::accept): Use event driven technique to implement
interuptible accept.
(fhandler_socket::wait): Allow FD_ACCEPT handling.
* net.cc (cygwin_accept): Remove workaround for allowing blocking
accept. That's entirely in fhandler_socket::accept now.
