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.
