Eric Auger 9a85e4b8f6 migration: Support gtree migration ... Introduce support for GTree migration. A custom save/restore is implemented. Each item is made of a key and a data. If the key is a pointer to an object, 2 VMSDs are passed into the GTree VMStateField. When putting the items, the tree is traversed in sorted order by g_tree_foreach. On the get() path, gtrees must be allocated using the proper key compare, key destroy and value destroy. This must be handled beforehand, for example in a pre_load method. Tests are added to test save/dump of structs containing gtrees including the virtio-iommu domain/mappings scenario.
