[NetworkManager-libreswan/lr/gtk-4.0: 5/7] editor: split setup of advanced dialog widgets off

[Lubomir Rintel <lkundrak src gnome org>]

commit 3b434edc40d628355adf6a2349d5a87b6cc63b45
Author: Lubomir Rintel <lkundrak v3 sk>

    editor: split setup of advanced dialog widgets off
    
    Currently the advanced dialog always remembers what's set, regardless of
    whether the user confirms it or dismisses it. This is not what users
    expect and we'll fix it in the following commit.
    
    Splitting off the widget setup and readback of values is done in
    preparation for that.
