Re: [libvirt] [PATCH v5 6/9] libxl: add support for CPUID features policy

Convert CPU features policy into libxl cpuid policy settings. Use new ("libxl") syntax, which allow to enable/disable specific bits, using host CPU as a base. For this reason, only "host-passthrough" mode is accepted. Libxl do not have distinction between "force" and "required" policy (there is only "force") and also between "forbid" and "disable" (there is only "disable"). So, merge them appropriately. If anything, "require" and "forbid" should be enforced outside of specific driver. Nested HVM (vmx and svm features) is handled separately, so exclude it from translation.
