Christian Borntraeger e73316d594 s390x/kvm: disable cpu model for the 2.7 machine
cpu model was merged with 2.8, it is wrong to abuse ri_allowed which
was enabled with 2.7.

Fan Zhang 9700230b0d s390x: enable runtime instrumentation
Introduce run-time-instrumentation support when running under kvm for
virtio-ccw 2.7 machine and make sure older machines can not enable it.

The new ri_allowed field in the s390MachineClass serves as an indicator
whether the feature can be used by the machine and should therefore be
activated if available.

riccb_needed() is used to check whether riccb is needed or not in live
migration.

Janosch Frank 8b8a61ad8c s390x: Introduce S390MachineClass
As we now have the new machine definitions, that let us disable/enable
machine options more easily, we need a way to save them and make them
publicly available.

The new s390-virtio-ccw.h header exports the s390 ccw machine state
and class, so they can be easily used in other C files.
