The switch to emulate_invalid_guest_state brought one slightly unwelcome change; the debugging interface does not work in the initial boot phase because KVM_SET_GUEST_DEBUG is basically ignored.
These two patches bring some initial support for debugging, namely for hardware breakpoints and single-stepping. Software breakpoints and hardware watchpoints are still ignored.

v1->v2: rename EMULATE_DO_MMIO to EMULATE_USER_EXIT; return EMULATE_* value via pointer-to-int argument.
