[PATCH v3 5/7] qemu_capabilities: filter deprecated features if requested
If flag VIR_CONNECT_GET_DOMAIN_CAPABILITIES_DISABLE_DEPRECATED_FEATURES
is passed to qemuConnectGetDomainCapabilities, then the domain's CPU
model features will be updated to set any deprecated features to the
'disabled' policy.
