virDomainDiskSourceParse got to the point of being an ugly spaghetti mess by adding more and more stuff into it. Split out parsing of network disk information into a separate function so that it stays contained. --- I've had this patch on a branch that makes virDomainDiskSourceParse uglier, but with the recent VxHS patches I've got a merge conflict, thus I'm sending it now.
