Then we already have the bogus situation, where libvirt.c is silently
filtering out internal flags.

Either we must not use the public flags argument for internal flags (and
thus fix driver.h to give the callback an internalFlags argument), or we
are already publicly limited to at most 16 bits for virDomainGetXMLDesc
due to older clients silently ignoring the upper bits.
