This moves exception injection to svm_check_nested_events, which is very pleasing: it cleans up the recently introduced #DB handling, removes exit_required, and fixes #UD trapping in the guest (for example from an RSM instruction, as tested in kvm-unit-tests). As a bonus, the last patch adds INIT vmexit injection to svm_check_nested_events as well. Note that there is no test case for that yet. The patches have small conflicts with those I posted yesterday, so they are on top of them.
