More porting to GCC 8 of --enable-gcc-warnings

* lwlib/lwlib-Xaw.h (xaw_update_one_value, xaw_popup_menu):
* lwlib/lwlib-Xlw.h (xlw_update_one_value, xlw_pop_instance):
* lwlib/lwlib.h (lw_allow_resizing, lw_set_main_areas) [!USE_MOTIF]:
No longer const.
* src/emacs-module.c: Ignore -Wcast-function-type.
