If VIR_DOMAIN_XML_COMMON_FLAGS gains a new flag, we don't want these callers to start outputting new information merely because they used the convenience macro. (That is, the macro is good for virCheckFlags(), to allow a driver to automatically support a new public flag by deferring to the common domain_conf implementation's support of the new flag; but it is not good for internal uses where we are generating specific output without regards to flags passed in through the public API).
