[libvirt PATCH 09/11] qemu_capabilities: Translate CPU blockers
The list of features reported by QEMU as blocking a particular CPU model
on the current host cannot be directly used by libvirt (or its users) as
QEMU uses different names for some features. We need to translate them
before using them or presenting them to users.
