Log Message:
Pull up following revision(s) (requested by bouyer in ticket #1625):
        sys/arch/xen/xen/xencons.c: revision 1.20
- Add or change memory barrier to reflect the related operation
- In xencons_handler(), update in_cons inside the loop, otherwise,
  we would trigger the xenconscn_getc() workaround wich reset cons and prod
  to their original values, and this creates an infinite loop
Should fix the console hang reported by several users on port-xen@.
