This introduces
- a (generic) config setting to turn on compatibility mode support
- support to load a Dom0 32-bit ELF image on 64-bit
- a compatibility guest mode GDT (requires moving the ring 0
  selectors to different GDT slots), and the respective selector
  handling changes
- some initial code path changes to address the needs of a
  compatibility mode guest

This changes the ABI in adding to vcpu_guest_context - does a change like
this require bumping the ABI version?
