mutter/src/backends/meta-remote-desktop-session.c
Jonas Ådahl ac1a5366b1 remote-desktop/session: Added boiler plate for clipboard integration 
Nothing is hooked up, it only does basic sanity checking i.e. whether
the clipboard was enabled when interacting with it. No actual clipboard
integration is hooked up yet.

This also syncs org.gnome.Mutter.RemoteDesktop.xml from
gnome-remote-desktop.
