Compilation fixes for wx{X11,GTK1,Motif} after making ref data non copyable.

Don't use wrong compiler-generated copy ctors in the other ports neither (see
r66371..66373 for wxGTK fixes). This fixes compilation after r66374 without
reducing functionality but just making it more clear where it is missing.
