[libadwaita/wip/exalm/window-rename: 1/3] Rename AdwWindow:child and AdwApplicationWindow:child to content




commit 3a4772f85847773e9248ab02b2b9f3979150da53
Author: Alexander Mikhaylenko <alexm gnome org>
Date:   Tue Aug 31 14:33:07 2021 +0500

    Rename AdwWindow:child and AdwApplicationWindow:child to content
    
    Avoid a name clash with gtk_window_set_child() etc.
    
    Fixes https://gitlab.gnome.org/GNOME/libadwaita/-/issues/255
