[eel-gtk-extension] remove unused eel_gtk_adjustment_* functions

we've deprecated them in commits 99f8b5f and 02affda
[(list|tree)-model] use GdkPixbuf/GIcon interface to set emblems

So that emblems get composited for us also on pixbufs such as thumbnails.

[icon-container] apply emblems directly on the pixbuf

Do that before setting the pixbuf to the CajaIconCanvasItem,
so the logic there can be removed.

[icon-container] don't care anymore about the emblem size

Use only GIcons for emblems, not pixbufs. We used to rely on pixbufs to
get emblems at a specific size, but that's not important anymore now
that GTK+ takes care of it internally.
