[libvirt] [PATCH v3 1/2] qemu: formatting XML from domain def choosing the root name

[Maxiwell S. Garcia]

The function virDomainDefFormatInternal() has the predefined root name
"domain" to format the XML. But to save both active and inactive domain
in the snapshot XML, the new root name "inactiveDomain" was created.
So, this function was modified to be driven by the new flag
VIR_DOMAIN_DEF_FORMAT_INACTIVE_NODE to choose the correct root name.
