For the single-binary, we want to be able to retrieve at runtime the current target among the different ones available. A consequence is that we can't rely on existing target_info() definition since it will create a conflict once more than one target is available. To solve this, we add TargetInfo in QOM, with this hierarchy. We define one class "target-info-X" per target, that inherits from abstract class "target-info". Using concrete vs abstract class ensure we can easily filter "target-info-X" from all QOM types. Associated TargetInfo is directly set through class initialization, without relying on any instance. For user mode, we simply define target_info() like it was done previously. In this patch, we keep the same definition for system-mode also, and it will be replaced in next commits. We will introduce detection of target from QOM, so we need to make sure those types are registered early.
