    wayland: Rename set_transient_for to set_parent
    
    This is also something that we did upstream. Since we want to
    introduce an explicit "xdg_transient" window type for tooltips
    and popovers, and since "transient_for" is a confusing dumb
    80s term lifted from the ICCCM spec, just rename it.

-       Setting a surface as transient of another means that it is child
-       of another surface.
-
        Child surfaces are stacked above their parents, and will be
        unmapped if the parent is unmapped too. They should not appear
        on task bars and alt+tab.
