(specific to 4.1): don't put CLIENT_LOCAL_FILES in
CLIENT_CAPABILITIES; it would make mysql_options(CLIENT_LOCAL_FILES,0)
have no effect.


libmysql/client_settings.h:
  Don't enforce that we client have CLIENT_LOCAL_FILES;
  indeed this CLIENT_CAPABILITIES is used as minimum
  client options in mysql_real_connect(), which is *after*
  mysql_options(). Having CLIENT_LOCAL_FILES in
  CLIENT_CAPABILITIES defeats disabling it in mysql_options().
