Subject: * eval.c (rb_mod_define_method): define_method should follow  
 default method visibility.

* eval.c (rb_attr): should warn if the default method visibility
  is "module_function" (can be error).

* eval.c (rb_mod_define_method): should define class/module method
  also if the visibility is "module_function".

* eval.c (rb_mod_define_method): should call hook method
  "method_added", and "singleton_method_added".

* string.c: use RESIZE_CAPA for capacity change.

* ext/socket/socket.c (Init_socket): add listen method to
  TCPServer and UNIXServer.

* ext/socket/socket.c (bsock_send): should raise EWOULDBLOCK
  exception.

* ext/socket/socket.c (s_recvfrom): ditto.

* ext/socket/socket.c (s_accept): ditto.

* ext/socket/socket.c (udp_send): ditto.
