Subject: [PATCH] qemu: formatting XML from domain def choosing the root name

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, the new function virDomainDefFormatInternalSetRootName() allows to
choose the root name of XML. The former function became a tiny wrapper
to call the new function setting the correct parameters.
