commit 38d81be6392f335fb67b198afe2227504dabace5

wayland: Replace clipboard implementation
The wayland specific clipboard functions have been replaced by something
more similar to the hooking the win32 backend does, which allows for just
using the default GtkClipboard code in GTK+. As a consequence, the
wayland-specific GtkClipboard implementation is now gone.
