xend: Properly save/restore vnc/vfb configuration

In 19284:0942BAA2A088 provision was made for running vnc and sdl
simultaneously.  However, arrangements for saving and restoring the
new structure-configuration, and arrangements for allowing the new
code to load old savefiles, were not made.

This patch adds these facilities.  Amongst other things, HVM VNC
save/restore will now work properly again.
