When decoding CPUID data to virCPUDef we need to be careful about using
a CPU model which cannot be directly used on the current host. Normally,
libvirt would notice the features which prevent the model from being
usable and it would disable them in the computed virCPUDef, but this
won't work in case the definition of the CPU model in QEMU contains more
features than what we have in cpu_map.xml. We need to count with the
usability blockers we got from QEMU and explicitly disable all of them
to make the computed virCPUDef usable.

Jiri Denemark (23):
util: Introduce virStringListCopy
conf: Add usability blockers to virDomainCapsCPUModel
qemu: Store CPU usability blockers in caps cache
qemu: Parse unavailable features for CPU models
cpu: Use virDomainCapsCPUModelsPtr in cpu driver APIs
cpu: Drop unused parameter from cpuDecode
cpu: Return model from virCPUModelIsAllowed
cpu_x86: Move x86FeatureFind* to avoid forward prototypes
cpu_x86: Disable blockers from unusable CPU models
cputest: Replace json bool with enum
cputest: Avoid calling json_reformat in cpu-parse.sh
cputest: Print correct feature in virCPUUpdateLive test
cputest: Test CPU usability blockers
cputest: Separate QEMUCaps creation from cpuTestCPUIDJson
build: Export virCPUModelIsAllowed private API
cputest: Use CPU models from QEMU when available
cputest: Add query-cpu-definitions reply for Core-i5-2540M
cputest: Add CPUID data for Intel(R) Xeon(R) CPU E7-4830
cputest: Add query-cpu-definitions reply for Xeon-E7-4830
cputest: Update Xeon-E3-1245 data
cputest: Add query-cpu-definitions reply for Xeon-E3-1245
cputest: Update Core-i7-2600 data
cputest: Make a crippled version of Core-i7-2600
