Subject: [PATCH 0/4] KVM: nSVM: more svm_check_nested_events work

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.
