Every time a vCPU is hot-plugged, it will "inherit" its tracing state from the global state array. That is, if *any* existing vCPU has an event enabled, new vCPUs will have too.

Instead of checking both env->features and ena_mask at two different places in the CPUID code, initialize ena_mask based on the features that are enabled for the CPU, and then clear unsupported bits based on kvm_arch_get_supported_cpuid(). The results should be exactly the same, but it will make it easier to move the mask calculation elsewhare, and reuse x86_cpu_filter_features() for the kvm_arch_get_supported_cpuid() check.

The code that calculates the set of supported XSAVE components on CPUID looks at ext_save_areas to find out which components should be enabled. However, if there are zeroed entries in the ext_save_areas array, the ((env->features[esa->feature] & esa->bits) == esa->bits) check will always succeed and QEMU will unconditionally try to enable the component. Luckily this never caused any problems because the only missing entry in ext_save_areas is the PT State component (bit 8), and KVM currently doesn't support it (so it was cleared on ena_mask). But the code was still incorrect and would break if KVM starts returning CPUID[EAX=0xD,ECX=0].EAX[bit 8] as supported on GET_SUPPORTED_CPUID. Fix the problem by changing the code to not enable a XSAVE component if ExtSaveArea::bits is zero.

Instead of requiring users and management software to be aware of required CPUID level/xlevel/xlevel2 values for each feature, automatically increase those values when features need them. This was already done for CPUID[7].EBX, and is now made generic for all CPUID feature flags. Unit test included, to make sure we don't break ABI on older machine-types and don't mess with the CPUID level values if they are explicitly set by the user.
