s390/sclp: add sclp_get_ibc function
KVM: s390: split SIE state guest prefix field
KVM: s390: use facilities and cpu_id per KVM
KVM: s390: add ibc api

Please don't ask in riddles... :-)
S390ProcessorProps are attributes that represent cpu model related properties
of the processor.

- comment for AccelCpuInfo type updated (13/16)
- routine s390_facility_test() factored out (15/16)
v1-v2:
- QEMU-side facility list mask introduced: this allows to enable guest
facilities that are handled by instruction interception handler
u_aliases(), adds cu model aliases
- s390_cpu_classes_initialized(), test if cpu classes have been initialized
- s390_fac_list_mask_by_machine(), returns facility list mask by machine
- s390_current_fac_list_mask(), returns facility list mask of current machine

The patch introduces routine s390_facility_test() which allows to
verify a specific facility bit is set.

The patch adds optional parameters to the QMP command query-cpu-definitions.
Thus the signature of routine arch_query_cpu_definitions needs to be changed
