xen: add framebuffer backend driver (Gerd Hoffmann) 

This patch adds a frsamebuffer (and kbd+mouse) backend driver.  It
it based on current xen-unstable code.  It has been changed to make
use of the common backend driver code.  It also has been changed to
compile with xen headers older than release 3.3
