Looks good to me.

Apart from addons/res_config_mysql.c, I think you got them all.

The other changes should be fine too since the paramater ap in res_config_odbc isn't ended in any of the adapter functions there. I'm a little wary though that they should be copying to a new va_arg list instead like res_config_odbc does.
