[António Fernandes <antoniof src gnome org>]

commit 67812f918d0162de0bc7cf0325d7eedc2d3f85bb

    eel-stock-dialogs: Add eel_show_simple_dialog
    
    Extracts the creation of simple dialogs to a new function
    that does not depend on gtk_dialog_run. It is the caller's
    responsibility to obtain a response from the dialog.
    
    Part of #1992
