Jean, Anthony, This series contains a bunch of straightforward extensions to the suite of functions and macros for using in VMStateDescription structures. Mostly these fill fairly obvious gaps in the existing set, though the last adds genuinely new feature (but is still pretty simple).
Obviously, these aren't being used in the savevm code already in the tree, but I need them for my work-in-progress patches fixing / adding savevm support for ppc guests. Please apply.
